Quad 2-Channel Multiplexer
The TC74ACT157 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 may be used as a level converter for interfacing
TTL or NMOS to High Speed CMOS. The inputs are compatible
with TTL, NMOS and CMOS output voltage levles.
This device consist of four 2-input digital multiplexer with
common select and strobe inputs.
When the ST 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: t_pd = 5.1 ns (typ.) at V_CC = 5 V
• Low power dissipation: I_CC = 8 μA (max) at Ta = 25°C
• Compatible with TTL outputs: V_IL = 0.8 V (max)
V_IH = 2.0 V (min)
• Symmetrical output impedance: |I_OH| = I_OL = 24 mA (min)
Capability of driving 50 Ω
transmission lines.
• Balanced propagation delays: t_pLH ^∼− t_pHL
• Pin and function compatible with 74F157
Note: xxxFN (JEDEC SOP) is not available in
Japan.
