74F189 - 64-Bit RAM

Datasheet Summary

Description

The F189 is a high-speed 64-bit RAM organized as a 16word by 4-bit array.

Address inputs are buffered to minimize loading and are fully decoded on-chip.

The outputs are 3-STATE and are in the high impedance state whenever the Chip Select (CS) input is HIGH.

Features

s 3-STATE outputs for data bus.

74F189 64-Bit Random Access Memory with 3-STATE Outputs April 1988 Revised June 2002 74F189 64-Bit Random Access Memory with 3-STATE Outputs General Description The F189 is a high-speed 64-bit RAM organized as a 16word by 4-bit array. Address inputs are buffered to minimize loading and are fully decoded on-chip. The outputs are 3-STATE and are in the high impedance state whenever the Chip Select (CS) input is HIGH. The outputs are active only in the Read mode and the output data is the complement of the stored data.
