SYNCHRONOUS
DUAL-PORT RAM
IDT70914S
Features
x High-speed clock-to-data output times
– Military: 20/25ns (max.)
– Commercial: 12/15/20ns (max.)
x Low-power operation
– IDT70914S
Active: 850 mW (typ.)
Standby: 50 mW (typ.)
x Architecture based on Dual-Port RAM cells
– Allows full simultaneous access from both ports
x 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
x TTL-compatible, single 5V (+ 10%) power supply
x Clock Enable feature
x Guaranteed data output hold times
x Available in 68-pin PLCC, and 80-pin TQFP

NOTES:
3490 tbl 06b
1. At fMAX, address and control lines (except Output Enable) are cycling at the maximum frequency clock cycle of 1/tCYC, using "AC TEST CONDITIONS" at input levels
of GND to 3V.
2. f = 0 means no address, clock, or control lines change. Applies only to input at CMOS level standby.
3. Port "A" may be either left or right port. Port "B" is the opposite from port "A".
4. Vcc = 5V, TA = 25°C for Typ, and are not production tested. ICC DC = 150mA (Typ).
5. Industrial temperature: for specific speeds, packages and powers contact your sales office.
