TC74ACT151P/F is an ultra-fast 8-channel multiplexer with positive and reverse outputs produced by Toshiba Corporation. The input is TTL level and can be directly connected to the TTL level bus. The features are fast speed, low power consumption, and can match high-speed Schottky TTL.
The TC74ACT151P/F is an 8‑channel multiplexer built with 2‑layer metal, silicon‑gate CMOS technology, offering both non‑inverting (Y) and inverting (W) outputs. It accepts TTL‑level inputs, includes input‑protecting diodes, and provides a fast propagation delay of about 7 ns.
The datasheet lists absolute maximum ratings, operating conditions, and electrical characteristics such as supply voltage (4.5‑5.5 V), input voltage thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V), output current capabilities (I_OH ≥ 24 mA, I_OL ≥ 50 mA), and temperature range (‑40 °C to 85 °C). Package options are DIP‑16 (1.00 g) and SOP‑16 (0.18 g) with detailed pin‑out diagrams. This manual is written in Japanese.
