TC74ACT573

The TC74ACT573 is an advanced high speed CMOS OCTAL LATCH fabricated with silicon gate and double-layer metal wiring C2MOS technology.It achieves the high speed operation similar to  equivalent bipolar schottky TTL while maintaining the CMOS low power dissipation.This device may be used as a level converter for interfacing TTL or NMOS to High speed CMOS.The inputs  are compatible with TTL, NMOS and CMOS output voltage levels.These 8-bit D-type latches are controlled by a latch enable(LE) and a output enable input (OE).When the OE input is high, the eight outputs are in a high impedance state.All inputs are equipped with protection circuits against static discharge or transient excess voltage.

Features of the TC74ACT573 are:(1)high speed:tpd=5.5ns (typ.) at Vcc=5V; (2)Low Power Dissipation:Icc=8A(Max.) at Ta=25; (3)compatible with TTL outputs:Vil=0.8V (max.),Vih=2.0V (min.); (4)symmetrical output impedance:|Ioh|=IoL=24mA (min. capability of driving 50 transmission lines; (5)balanced propagation delays:tplh=tphl; (6)pin and function compatible with 74F573.

The absolute maximum ratings of the TC74ACT573 can be summarized as:(1)supply voltage range:-0.5 to 7.0V;(2)storage temperature:-65 to 150;(3)DC input voltage:-0.5 to Vcc+0.5 V;(4)DC output voltage:-0.5 to Vcc+0.5 V;(5)power dissipation:500mW.The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics.
