Speed obtained with High Speed AC measurement conditions. This publication supersedes and replaces all information previously supplied.
Exposure to Absolute Maximum Rating condi- tions for extended periods may affect device reliability. A new pattern can then be written to the device by 72c1001 the programming procedure. Two Line Output Control Because EPROMs are usually used in larger memory arrays, this product features a 2 line con- trol function which accommodates the use of mul- datasneet memory connection.
Output Enable G is the output control and should be used to gate data to the output pins, indepen. Vcc is specified to be 6. A 27f1001 power 27c001 ply is required in the read mode. Chip Enable E is the power control and shoUd be used for device selection. The FDIP32W window ceramic frit-seal package and the LCCC32W leadless chip carrier package have a transparent lids which allow the user to ex- pose the chip to ultraviolet light to erase the bit pat- tern.
This ensures that all deselect- ed memory devices are in their low power standby mode and that the output pins are only active when data is required from a particular memory device.
Except for the rating “Operating Temperature Range”, stresses above tinose iisted in tiie Tabie “Absolute Maximum Ratings” may cause permanent damage to the device. Address Transition to Output Transition. Two Line Output Control Because EPROMs are usually used in larger memory arrays, this product features a 2 line con- trol function which accommodates the use of mul- tiple memory connection. These are stress ratings daatsheet and operation of the device at these or any other conditions above those indicated in the Operating sections of this specification is not implied.
For the most efficient use of these two control lines, E should be decoded and used as the prima- ry device selecting function, while G should be made a common connection to all devices in the array 27v1001 connected to the READ line from the system control bus. I PP Program Current. The supply current, Ice, has three seg- ments that are of interest to the system designer: The datasehet transient voltage peaks 27d1001 be suppressed by complying with the two line output control and by properly selected decoupling capacitors.
Ail other address lines must be held at Vil during Electronic Signature mode. Read Mode The M27C has two control functions, both of which must be logically active in order to obtain data at the outputs.
It should be noted that sunlight and some type of fluorescent lamps have wavelengths in the A range. This ensures that datahseet deselect. AC Testing Load Circuit dtaasheet. High Speed, see AC Characteristics section for further information. When in the standby mode, the outputs are in a high imped- ance state, independent of the G input.

Read Mode AC Characteristics 1. Address Valid to Output Valid. Vcc must be applied simuitaneously with or before Vpp and removed simultaneously or after Vpp. Maximum DC voltage on Output is V. A new pattern can then be written to the device by following the programming procedure.
Ordering Information Scheme Example: Arrow Electronics Mouser Electronics. For a list of available options Speed, Package, etc. Speed obtained with High Speed 271001 measurement conditions. It is ideally suited for micro- processor systems requiring large programs and is organized aswords of 8 bits. It offers a large amount of data sheet, You can free PDF files download.
The M27C is in the programming mode when Vpp input is at Test Condition 3.
