MC74VHCT373A Octal DType Latch with 3State Output The MC74VHCT373A 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 VHCT inputs are compatible with TTL levels. This device can be used as a level converter for interfacing 3.3 V to 5.0 V, because it has full 5.0 V CMOS level output swings. The VHCT373A input and output (when disabled) structures provide protection when voltages between 0 V and 5.5 V are applied, regardless of the supply voltage. These input and output structures help prevent device destruction caused by supply voltageinput/output voltage mismatch, battery backup, hot insertion, etc. Features http://onsemi.com MARKING DIAGRAMS 20 VHCT373A AWLYYWWG 1 1 SOIC20WB SUFFIX DW CASE 751D 20 VHCT 373A ALYWG G 1 High Speed: tPD = 7.7 ns (Typ) at VCC = 5.0 V Low Power Dissipation: ICC = 4 mA (Max) at TA = 25°C TTLCompatible Inputs: VIL = 0.8 V; VIH = 2.0 V Power Down Protection Provided on Inputs and Outputs Balanced Propagation Delays Designed for 4.5 V to 5.5 V Operating ……
