The TC74AC151 is an advanced high-speed CMOS 8-CHANNEL MULTIPLEXER fabricated with silicon gate and double-layer metal wiring C2MOS technology. It achieves high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining low power dissipation. One of eight data input signals (D0-D7) is selected by decoding the three-bit address input (A, B, C). The selected data appears on two outputs: non-inverting (Y) and inverting (W). The STROBE input provides two output conditions; a low level on the STROBE input transfers the selected data to the outputs. A high level on the STROBE input sets the Y output low and the W output high without regard to the data or select input conditions. All inputs are equipped with protection circuits against static discharge or transient excess voltage.
The TC74AC151 is an advanced high‑speed CMOS 8‑channel multiplexer fabricated with silicon gate and double‑layer metal wiring C2MOS technology. It selects one of eight data inputs (D0‑D7) using a three‑bit address and provides both non‑inverting (Y) and inverting (W) outputs. The STROBE input controls output states, and all inputs have static‑discharge protection.
The device operates from 2.0 V to 5.5 V supply voltage, offers typical propagation delays of about 5 ns, and can drive up to 24 mA output current. Package options include DIP‑16, SOP‑16, and SOL‑16 with typical weights of 1.00 g, 0.18 g, and 0.13 g respectively. The datasheet also includes absolute maximum ratings, electrical characteristics, and usage restrictions.
