– Fast 12ns clock to data out

– Military:20/25ns(max.)

– Commercial:12/15/20ns (max.)

– Self-timedwriteallowsfastcycletimes

– 16ns cycletimes,60MHzoperation

◆

Low-power operation

– IDT70914S

Active: 850 mW (typ.)

Standby: 50 mW (typ.)

Architecture based on Dual-Port RAM cells

– Allowsfullsimultaneousaccessfrombothports

Synchronous operation

– 4ns setup to clock, 1ns hold on all control, data, and address

inputs

– Data input, address, and control registers

TTL-compatible, single 5V (+ 10%) power supply

Clock Enable feature

Guaranteed data output hold times

Available in 68-pin PLCC, and 80-pin TQFP

Military product compliant to MIL-PRF-38535 QML

Industrial temperature range (-40°C to +85°C) is available

for selected speeds.

Recommended for replacement of IDT7099 (4K x 9) if

separate 9th bit data control signals are not required
