Quad 2-Channel Multiplexer
The TC74AC157 is an advanced high speed CMOS QUAD
2-CHANNEL MULTIPLEXER fabricated with silicon gate and
double-layer metal wiring C2MOS technology.
It achieves the high speed operation similar to equivalent
Bipolar Schottky TTL while maintaining the CMOS low power
dissipation.
This device consist of four 2-input digital multiplexer with
common select and strobe inputs.
When the STROBE input is held “H” level, selection of data
is inhibited and all the outputs become “L” level.
The SELECT decoding determines whether the A or B inputs
get routed to their corresponding Y outputs.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Features
High speed: tpd = 4.5 ns (typ.) at VCC = 5 V
Low power dissipation: ICC = 8 μA (max) at Ta = 25°C
High noise immunity: VNIH = VNIL = 28% VCC (min)
Symmetrical output impedance: |IOH| = IOL = 24 mA (min)
Capability of driving 50 Ω
transmission lines.
Balanced propagation delays: tpLH ∼− tpHL
Wide operating voltage range: VCC (opr) = 2 to 5.5 V
Pin and function compatible with 74F157
Note: xxxFN (JEDEC SOP) is not available in
Japan.
