74HC15174系列产品详情

The 74HC151 is a high speed CMOS 8-CHANNEL MULTIPLEXER fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. One of eight date input signals (D0-D7) is selected by decoding of 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.

Features

High speed: tpd = 15 ns (typ.) at VCC = 5 V

Low power dissipation: ICC = 4.0µA (max) at Ta = 25

Balanced propagation delays: tPLH ≈ tPHL

Wide operating voltage range: VCC(opr) = 2.0 to 6.0 V
