64-Bit Random Access Memory with TRI-STATE

Outputs

General Description

Features

TRI-STATE outputs for data bus applications

Buffered inputs minimize loading

Address decoding on-chip

The ’F219 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

TRI-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. This device is similar to the ’F189

but features non-inverting, rather than inverting, data out-

puts.

Diode clamped inputs minimize ringing

Available in SOIC (300 mil only)
