TC74HC670AF概述

4 Word × 4Bit Register File 3-state

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% VCCmin

• Output drive capability: 10 LSTTL loads

• Symmetrical output impedance: |IOH| =IOL =4 mA min

• Balanced propagation delays: tpLH∼ − tpHL

• Wide operating voltage range: VCCopr =2 to 6 V

• Pin and function compatible with 74LS670
