MC74VHC573 Octal DType Latch with 3State Output The MC74VHC573 is an advanced high speed CMOS octal latch with 3state 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 8bit Dtype 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 7V, allowing the interface of 5V systems to 3V systems. http://onsemi.com MARKING DIAGRAMS 20 20 1 SOIC20 WIDE DW SUFFIX CASE 751D 1 TSSOP20 DT SUFFIX CASE 948E 20 VHC573 AWLYYWW 20 VHC 573 ALYW 1 VHC573 AWLYYWW w High Speed: tPD = 4.5ns (Typ) at VCC = 5V Low Power Dissipation: ICC = 4μA (Max) at TA = 25°C High Noise Immunity: VNIH = VNIL = 28% VCC Power Down Protection Provided on Inputs Balanced Propagation Delays Designed for 2V to 5.5V Operating Range Low Noise: VOLP = 1.2V (Max) Pin and Function Compatible with Other Standard Logic Families Latchup Performance Exceeds 300mA ESD Performance: HBM > 2000V; Machine Model > 200V Chip Complexity: 218 FETs or 54.5 Equivalent Gates These devices are available in Pbfree package(s).
