DATA SHEET .onsemi. Octal D-Type Latch with 3-State Output MC74VHC373, MC74VHCT373A The MC74VHC373/MC74VHCT373A is an advanced high speed CMOS octal latch with 3- state output fabricated with silicon gate CMOS technology. The device achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. The MC74VHC373/MC74VHCT373A is an 8- bit D- type latch controlled by a latch enable input and an output enable input. When the output enable is high, the 8 outputs are in high impedance state. The MC74VHC373 inputs are patible with standard CMOS levels while the MC74VHCT373A inputs are patible with TTL levels. The MC74VHCT373A 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 internal circuit is posed of three stages, including a buffer output which provides high noise immunity and stable output. The MC74VHC373 and MC74VHCT373A input structures tolerate voltages up to 5.5 V, allowing the interface of 5 V systems to 3 V systems. The MC74VHCT373A output structures provide protection when VCC = 0 V. These output structures help prevent device destruction caused by supply voltage - input/output voltage mismatch, battery backup, hot insertion, etc. Features - High Speed: t PD = 5.0 ns (Typ) at VCC = 5.0 V (VHC) t PD = 7.7 ns (Typ) at VCC = 5.0 V (VHCT) - Low Power Dissipation: ICC = 4.0 m A (Max) at TA = 25°C - High Noise Immunity: VNIH = VNIL = 28% - Power Down Protection Provided - Balanced Propagation Delays - Designed for: 2.0 V to 5.5 V (VHC) 4.5 V to 5.5 V (VHCT) - Low Noise: VOLP = 0.9 V (Max) (VHC) VOLP = 1.6 V (Max) (VHCT) - Pin and Function patible with Other Standard Logic Families - Latchup Performance Exceeds 100 m A - ESD Performance: Human Body Model > 2000 V; - Chip plexity: 196 FETs or 49 Equivalent Gates - These Devices are Pb- Free, Halogen Free and are Ro HS pliant SOIC- 20 DW SUFFIX CASE 751D TSSOP- 20...
