Overview
The SN74LVC157APW is a quadruple 2-line to 1-line data selector/multiplexer manufactured by Texas Instruments in a 16-pin TSSOP package. It operates from a supply voltage of 1.65V to 3.6V and supports an operating temperature range of -40°C to 85°C. The device features inputs that accept voltages up to 5.5V, enabling compatibility with 5V logic systems. Maximum propagation delay is specified at 5.2ns at 3.3V, with typical output ground bounce of 2V.
Feature Summary
- Provides four independent 2-to-1 multiplexing channels controlled by a common address select input.
- Features a low-active strobe input that forces all outputs low when asserted high.
- Accepts 5.5V input signals, allowing direct interfacing between 3.3V and 5V logic domains.
Applications
- Translating data between mixed 3.3V and 5V system environments.
- Routing data from two groups of registers to four common output buses.
- Implementing irregular logic functions using the device as a function generator.
Procurement Notes
Verify the specific ordering suffix 'PW' corresponds to the TSSOP 16-pin tube packaging configuration. Confirm the active production status and RoHS compliance details via the manufacturer's official documentation before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring low-voltage operation down to 1.65V with robust 5V tolerance on inputs. Ensure the design accommodates the specified thermal resistance values for the TSSOP package under expected ambient conditions.
Part Context
This part belongs to the SNx4LVC157A family of quadruple multiplexers designed for CMOS low-voltage technology. The 'SN74' prefix indicates commercial grade availability, while the 'LVC' designation specifies the low-voltage CMOS process technology used for power efficiency.
Replacement Considerations
Compatible alternatives within the same family include SN74LVC157AD (SOIC) and SN74LVC157ANSR (SOP). Verify pinout compatibility and package dimensions when substituting different physical form factors.
