TC74AC139F Description

Short technical summary and product information.

The Toshiba TC74AC139F is an advanced high-speed CMOS 2-to-4 line decoder. Fabricated with silicon gate and double-layer metal wiring C2MOS technology, it achieves high-speed operation comparable to Bipolar Schottky TTL while maintaining low CMOS power dissipation.

 

Key features include a propagation delay of 5.9 ns at 5V, low quiescent current of 8 μA maximum at 25°C, and high noise immunity. The device operates over a wide voltage range from 2V to 5.5V and has symmetrical output impedance capable of driving 50 Ω transmission lines.

 

All inputs are equipped with protection circuits against static discharge or transient excess voltage. The active low enable input can be used for gating or as a data input for demultiplexing applications. When the enable input is held high, all four outputs are fixed at a high logic level, independent of the other inputs.

 

This decoder is pin and function compatible with the 74F139. Available package weights include DIP (1.00 g typ.), SOP (0.18 g typ.), SOL (0.13 g typ.), and TSSOP (0.06 g typ.).
