74F189SC概述

具有三态输出的64位随机存取存储器 64-Bit Random Access Memory with 3-STATE Outputs

General Description

The F189 is a high-speed 64-bit RAM organized as a 16-word by 4-bit array. Address inputs are buffered to mini

mize loading and are fully decoded on-chip. The outputs are 3-STATE and are in the high impedance state when

ever 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.

Features

■3-STATE outputs for data bus applications

■Buffered inputs minimize loading

■Address decoding on-chip

■Diode clamped inputs minimize ringing
