TC74VHCT373AFT

The Toshiba TC74VHCT373AFT is an advanced high-speed CMOS Octal D-Type Latch with 3-state output, fabricated using silicon gate C2MOS technology. This device achieves high-speed operation comparable to equivalent Bipolar Schottky TTL while maintaining the low power dissipation characteristic of CMOS technology.

This 8-bit D-type latch is controlled by a latch enable input (LE) and an output enable input (OE). When the OE input is high, the eight outputs are in a high impedance state. The input voltage levels are compatible with TTL output voltage, making this device suitable as a level converter for interfacing 3.3 V to 5 V systems. Input protection and output circuitry allow 0 to 5.5 V to be applied to the input and output pins without regard to the supply voltage, preventing device destruction due to mismatched voltages.

Key features include a typical propagation delay of 7.7 ns at VCC = 5 V, low power dissipation with a maximum ICC of 4 μA at 25°C, and TTL compatible input levels (VIL max 0.8 V, VIH min 2.0 V). It also provides power-down protection on all inputs and outputs and exhibits balanced propagation delays. The TC74VHCT373AFT is pin and function compatible with the 74 series 373 type.

The TC74VHCT373AFT is available in a TSSOP20 package, weighing approximately 0.08 g. This latch is designed for applications requiring high-speed data storage and buffering with reliable interfacing capabilities.
