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. Pinout: Pinout of 74HC157 IC Pin Number Pin Name Description 2,5,11,14 Input A This is the first input line of the 2:1 Multiplexer 3,6,10,13 Input B This is the second input line of the 2:1 Multiplexer 4,7,9,12 Output Y This is the output line pin of the Multiplexer 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

What is the function of the 74HC157 IC?
The 74HC157 is a quad 2-input multiplexer that selects one of two 4-bit data sources and routes it to the output based on the select (S) pin.
Can the 74HC157 be used with Arduino or Raspberry Pi?
Yes, it is fully compatible with 5V and 3.3V logic levels, making it suitable for use with Arduino, Raspberry Pi, and other microcontrollers.
What is the operating voltage range of 74HC157?
The IC operates from 2V to 6V, with optimal performance at 5V. It supports both TTL and CMOS logic standards.
How do I enable the 74HC157 multiplexer?
Connect the enable pin (E, pin 15) to ground (LOW) to activate the IC. When HIGH, all outputs are forced LOW regardless of inputs.
