MC74VHC573

MC74VHC573 Octal D-Type Latch with 3-State Output The MC74VHC573 is an advanced high speed CMOS octal latch with 3−state output fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. This 8−bit D−type latch is controlled by a latch enable input and an output enable input. When the output enable input is high, the eight outputs are in a high impedance state. The internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output. The inputs tolerate voltages up to 7 V, allowing the interface of 5 V systems to 3 V systems. High Speed: tPD = 4.5 ns (Typ) at VCC = 5 V Low Power Dissipation: ICC = 4 μA (Max) at TA = 25°C High Noise Immunity: VNIH = VNIL = 28% VCC Power Down Protection Provided on Inputs Balanced Propagation Delays Designed for 2 V to 5.5 V Operating Range Low Noise: VOLP = 1.2 V (Max) Pin and Function Compatible with Other Standard Logic Families Latchup Performance Exceeds 300 mA ESD Performance: HBM > 2000 V; Machine Model > 200 V Chip Complexity: 218 FETs or 54.5 Equivalent Gates These Devices are Pb−Free and are RoHS Compliant PIN ASSIGNMENT OE 1 D0 2 D1 3 D2 4 D3 5 D4 6 D5 7 D6 8 D7 9 GND 10 20 VCC 19 Q0 18 Q1 17 Q2 16 Q3 15 Q4 14 Q5 13 Q6 12 Q7 11 LE http://onsemi.com 20 1 20 1 MARKING DIAGRAMS 20 SOIC−20 DW SUFFIX CASE 751D VHC573 AWLYYWWG 1 20 TSSOP−20 DT...
