74F189A64-bit TTL bipolar RAM, inverting (3-State)

FEA TURES

•High speed performance

•Replaces 74F189

•Address access time: 8ns max vs 28ns for 74F189

•Power dissipation: 4.3mW/bit

•Schottky clamp TTL

•One chip enable

are fully decoded on chip. The outputs are in high impedance state whenever the chip enable (CE) is high. The outputs are active only in the READ mode (WE

= high) and the output data is the

complement of the stored data.

DESCRIPTION

The 74F189A is a high speed, 64-bit RAM organized as a 16-word by 4-bit array. Address inputs are buffered to minimize loading and

Definitions

Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For

detailed information see the relevant data sheet or data handbook. Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one

or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability.
