Nexperia USA Inc. 74LVC157APW,118

Overview

74LVC157APW,118 from Nexperia is a quad 2-input CMOS multiplexer with independent data select (S) and active-low enable (E) inputs, operating from 1.2 V to 3.6 V supply, supporting mixed-voltage translation between 3.3 V and 5 V logic domains, and featuring Schmitt-trigger inputs for noise immunity in industrial control and digital signal routing applications.

For engineers reviewing the 74LVC157APW,118 datasheet, 74LVC157APW,118 pinout, 74LVC157APW,118 application, or 74LVC157APW,118 equivalent, this device serves as a low-power, voltage-tolerant signal selector in FPGA I/O expansion, microcontroller peripheral multiplexing, test equipment channel switching, and legacy bus interface bridging where precise timing, rail-to-rail input compatibility, and -40 °C to +125 °C operation are required.

Technical Context

The 74LVC157APW implements four independent 2:1 multiplexers sharing one common select line (S) and one global active-low enable (E), with all inputs tolerant up to 5.5 V regardless of VCC level. Its Schmitt-trigger inputs accept slow-rising signals and reject noise, enabling robust operation in electrically noisy environments.

Propagation delays range from 1.0 ns to 12.8 ns depending on VCC and signal path (e.g., 2.7 ns typical at VCC = 3.3 V for data-to-output), while output skew is guaranteed ≤1.5 ns across all four channels, ensuring synchronized switching critical for parallel data paths and clock domain interfacing.

FAQ

Can the 74LVC157APW,118 operate with a 1.2 V supply and still accept 5 V inputs?

Yes. The device is specified for VCC = 1.2 V to 3.6 V and features overvoltage-tolerant inputs rated to 5.5 V. This allows direct connection of 5 V logic signals (e.g., legacy microcontrollers or sensors) while the IC itself runs at 1.2 V, eliminating external level-shifting circuitry and reducing BOM cost and board area.

What is the maximum clock/data toggle frequency supported by the 74LVC157APW,118?

Based on its typical propagation delay of 2.7 ns at VCC = 3.3 V and output skew ≤1.5 ns, the device supports reliable data routing up to approximately 150 MHz (1/(2 × t_pd)). For sustained high-frequency operation, ensure proper PCB layout with controlled impedance traces and localized decoupling to maintain signal integrity.

Does the enable (E) pin force outputs to high-impedance or to logic LOW?

The E pin is active LOW and forces all four outputs (1Y–4Y) to a defined logic LOW state-not high-impedance. When E is HIGH, outputs follow the selected input; when E is LOW, outputs are actively driven LOW. This behavior prevents bus contention in shared-bus architectures and simplifies downstream logic design.

Is the TSSOP16 package (SOT403-1) suitable for reflow soldering in high-volume production?

Yes. The SOT403-1 package is qualified for standard lead-free reflow profiles (J-STD-020), including peak temperatures up to 260 °C. Its thermal pad-less construction and 0.65 mm pitch are fully compatible with automated pick-and-place and reflow processes used in Class III electronics manufacturing.
