74HC157D CMOS Digital Integrated Circuits Silicon Monolithic 74HC157D 1. Functional Description Quad 2-Channel Multiplexer 2. General The 74HC157D is high speed CMOS 2-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. When STROBE is held high, selection of data is inhibited and all the outputs become low. The SELECT decoding determines whether the A or B inputs get transferred to their corresponding Y outputs. All inputs are equipped with protection circuits against static discharge or transient excess voltage. 3. Features (1) Wide operating temperature range: T = -40 to 125 (Note 1) opr (2) High speed: t = 10 ns (typ.) at V = 5 V pd CC (3) Low power dissipation: I = 4.0 A (max) at T = 25 CC a (4) Balanced propagation delays: t t PLH PHL (5) Wide operating voltage range: V = 2.0 to 6.0 V CC(opr) Note 1: Operating Range spec of T = -40 to 125 is applicable only for the products which manufactured after opr July 2020. 4.
