Product details
Quad 2-Input Multiplexer IC - 74HC157
The 74HC Series 74HC157 is a 16-Pin Quad 2-Input Multiplexer IC having 2V to 6V Operating Voltage range with 1uA Low Input current and high noise immunity. It selects 4 bits of data from two sources under the control of a common data select input (S). The enable input (E) is active LOW. When E is HIGH, all of the outputs (1Y to 4Y) are forced LOW regardless of all other input conditions.

1
Line Select (S)
The select pin selects one of the two input lines and gives it to the output line
15
Enable (E)
Active low pin. Grounded for normal operation
8
Ground
Connected to the ground of the system
16
Vcc
This pin powers the IC, typically +5V is used.
Also check 74LS161 Synch 4-Bit Counter. It has an operating voltage range of 4.5V to 5.5V and a temperature range of -55°C to +125°C
Also check 74HC151 IC ( 74HC151 - 8-Input Multiplexer IC), used as a Data Selector/Multiplexer with full on-chip decoding to select one of eight data sources based on a unique three-binary code at select inputs
