onsemi · Signal Switches, Multiplexers, Decoders · TSSOP-16

74VHC157MTCX from onsemi, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 S input Common Select input that determines whether the I0x or I1x inputs are routed to the outputs; must be held HIGH or LOW, not floating, and tolerates 0V to 5.5V.
2 I0a input Source 0 data input for channel a, routed to Za when S is LOW and E is LOW.
3 I1a input Source 1 data input for channel a, routed to Za when S is HIGH and E is LOW.
4 Za output Channel a multiplexer output, forced LOW when E is HIGH.
5 I0b input Source 0 data input for channel b, routed to Zb when S is LOW and E is LOW.
6 I1b input Source 1 data input for channel b, routed to Zb when S is HIGH and E is LOW.
7 Zb output Channel b multiplexer output, forced LOW when E is HIGH.
8 GND power_in Ground pin (0V reference).
9 Zd output Channel d multiplexer output, forced LOW when E is HIGH.
10 I1d input Source 1 data input for channel d, routed to Zd when S is HIGH and E is LOW.
11 I0d input Source 0 data input for channel d, routed to Zd when S is LOW and E is LOW.
12 Zc output Channel c multiplexer output, forced LOW when E is HIGH.
13 I1c input Source 1 data input for channel c, routed to Zc when S is HIGH and E is LOW.
14 I0c input Source 0 data input for channel c, routed to Zc when S is LOW and E is LOW.
15 E input Active-LOW Enable input; when HIGH all outputs are forced LOW regardless of other inputs.
16 VCC power_in Positive supply voltage, recommended 2.0V to 5.5V (absolute maximum 7.0V).
