TC74VHCT138AFT Description

Short technical summary and product information.

The Toshiba TC74VHCT138AFT is a high-speed CMOS 3-to-8 line decoder, built using silicon-gate CMOS technology. It offers low power consumption comparable to high-speed Schottky TTL. The device features TTL-level inputs, allowing direct connection to TTL-level buses and enabling level conversion from 3V to 5V systems.

 

When enabled, the decoder selects one of the eight outputs to be at a "L" level based on the 3-bit binary address input. Non-selected outputs remain at "H" level. The enable inputs facilitate cascading and application in memory address decoding. All input and output pins are power-down protected, allowing 5V input/output voltage regardless of the power supply voltage, making it suitable for 2-power supply interfaces, battery backup circuits, and hot-swapping applications.

 

Key electrical characteristics include a typical propagation delay of 7.6 ns at 5V supply and a maximum quiescent current of 4 µA at 25°C. The device operates within an industrial temperature range of -40°C to 85°C. It is available in a TSSOP-16 package.
