74F219

64-Bit Random Access Memory with 3-STATE Outputs

General Description

The 74F219 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. This device is similar to the

74F189 but features non-inverting, rather than inverting,

data outputs.

Features

s 3-STATE outputs for data bus applications

s Buffered inputs minimize loading

s Address decoding on-chip

s Diode clamped inputs minimize ringing

s Available in SOIC (300 mil only)
