Overview
TC74HC157,158AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HC157AP, TC74HC157AF TC74HC158AP, TC74HC158AF TC74HC157AP/AF TC74HC158AP/AF Quad 2-Channel Multiplexer Quad 2-Channel Multiplexer (inverting) TC74HC157AP, TC74HC158AP The TC74HC157A and TC74HC158A are high speed CMOS 2-CHANNEL MULTIPLEXERs fabricated with silicon gate C2MOS technology.
They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation.
The TC74HC158A is an inverting multiplexer while the TC74HC157A is a non-inverting.
When STROBE is held high, selection of data is inhibited and all the outputs become low in the case of HC157A or high in the case of HC158A.
The SELECT decoding determines whether the A or B inputs get transferred to their corresponding Y ( Y ) outputs.
All inputs are equipped with protection circuits against static discharge or transient excess voltage.
Features • High speed: tpd = 10 ns (typ.
) at VCC = 5 V • Low power dissipation: ICC = 4 μA (max) at Ta = 25°C • High noise immunity: VNIH = VNIL = 28% VCC (min) • Output drive capability: 10 LSTTL loads • Symmetrical output impedance: |IOH| = IOL = 4 mA (min) • Balanced propagation delays: tpLH ∼− tpHL • Wide operating voltage range: VCC (opr) = 2 to 6 V • Pin and function compatible with 74LS157/158 TC74HC157AF, TC74HC158AF Weight DIP16-P-300-2.
