Package

The 74LVC157AD is typically packaged in a 16-pin TSSOP (Thin Shrink Small Outline Package) or similar surface-mount packages.

Pinout

The 74LVC157AD is a quad 2-to-1 multiplexer with a total of 16 pins. Its primary function is to select one of two inputs (A or B) for each of the four channels, based on a common select input (S).
Here's a breakdown of the pin configuration:
- Inputs (A0-A3, B0-B3): Four pairs of inputs (A and B) for each multiplexer channel.
- Select (S): Common select input to choose between A and B for each channel.
- Outputs (Y0-Y3): Four output pins that reflect the selected input.
- Enable (G): Active LOW enable input that must be asserted for the device to operate.
- VCC: Power supply pin (typically 1.2V to 3.6V).
- GND: Ground pin.
The device is commonly used in digital applications for data routing and signal multiplexing.
