The TC74HC670A is a high speed 4-WORDS× 4-BITS REGISTER FILE fabricatedwith silicon gate C2

MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.

Features

? High speed: tpd =23 ns (typ.) at VCC =5 V

? Low power dissipation: ICC =4 μA (max) at Ta =25°C

? High noise immunity: VNIH =VNIL =28 VCC(min)

? Output drive capability: 10 LSTTL loads

? Symmetrical output impedance: |IOH| =IOL =4 mA (min)

? Balanced propagation delays: tpLH～ ? tpHL

? Wide operating voltage range: VCC(opr) =2 to 6 V

? Pin and function compatible with 74LS670
