HIGH SPEED 36K (4K X 9)

SYNCHRONOUS

DUAL-PORT RAM

Features

IDT70914S

High-speed clock-to-data output times

– Military: 20/25ns (max.)

– Commercial: 12/15/20ns (max.)

Low-power operation

– IDT70914S

Active: 850 mW (typ.)

Standby: 50 mW (typ.)

Architecture based on Dual-Port RAM cells

– Allows full simultaneous access from both ports

Synchronous operation

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

inputs

– Data input, address, and control registers

– Fast 12ns clock to data out

– Self-timed write allows fast cycle times

– 16ns cycle times, 60MHz operation

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.
