Présentation
Description
The SN74LVC157ADR features four 2-to-1 multiplexers, enabling the selection of one of two data sources for each output. It is controlled via a common select line, and it also includes an active-low enable input that can disable the device to conserve power. The multiplexer ensures low power consumption and high-speed operation, achieving propagation delays typical of 5.5 ns at 3.3 V.
The package type, "ADR," indicates it is available in a small outline integrated circuit (SOIC) package, which is suitable for surface mounting. This makes it ideal for applications requiring efficient space utilization and reliability, such as data routing, signal gating, and bus management in digital systems.

Pinout
Pin Count and Functions:
- Pins: 16
- VCC (Pin 16): Supply voltage.
- GND (Pin 8): Ground.
- A, B (Pins 1, 3, 5, 11 for A0-A3 and 2, 4, 6, 10 for B0-B3): Data inputs from two sources.
- Y (Pins 7, 9, 12, 15): Multiplexed data outputs.
- S (Pin 14): Select input to choose between data sources (A or B).
- OE (Pin 13): Output enable, active low. When high, outputs are in high-impedance state.
This IC is widely used in applications requiring data routing and selection, including digital systems where multiple data lines need to be directed through a single channel.
