Texas Instruments SN74LV157ADGVR

Overview

SN74LV157ADGVR from Texas Instruments is a quadruple 2-line to 1-line data selector/multiplexer operating from 2 V to 5.5 V, delivering 7.5 ns max propagation delay at 5 V, supporting 5.5 V-tolerant inputs, and rated for –40°C to +85°C industrial temperature range - used in LED display data routing and network switch I/O path selection.

For engineers reviewing the SN74LV157ADGVR datasheet, SN74LV157ADGVR pinout, SN74LV157ADGVR application, or SN74LV157ADGVR equivalent, key selection criteria include supply voltage flexibility (2–5.5 V), input overvoltage tolerance, low ground bounce (<0.8 V), latch-up immunity (>100 mA), and TVSOP-16 package compatibility with high-density PCB layouts.

Technical Context

The SN74LV157ADGVR implements four independent 2:1 multiplexers with a common active-low output strobe (G) and shared address select (A/B) control, enabling simultaneous selection of one of two 4-bit data sources. Each channel routes true (non-inverted) data from selected input A or B to its corresponding Y output.

It features TTL-compatible input thresholds across its full 2–5.5 V VCC range, supports 15 pF and 50 pF load conditions, and maintains specified switching performance under –40°C to +85°C ambient operation - verified per JESD78 Class II latch-up testing and JEDEC HBM ±2000 V ESD rating.

Key Specifications

Pinout & Package

SN74LV157ADGVR is housed in a 16-pin TVSOP (DGV) package measuring 3.6 mm × 4.4 mm with 0.5 mm pitch, optimized for space-constrained applications requiring fine-pitch surface-mount assembly.

FAQ

What is the maximum propagation delay of the SN74LV157ADGVR at 3.3 V supply?

The SN74LV157ADGVR exhibits a typical propagation delay of 5.21 ns and a maximum of 11.5 ns at VCC = 3.3 V ± 0.3 V with a 15 pF load and TA = 25°C. This delay remains consistent across all four channels and is measured from address (A/B) or strobe (G) input transition to corresponding Y output transition.

Does the SN74LV157ADGVR support 5 V logic inputs when powered from 3.3 V?

Yes, the SN74LV157ADGVR accepts input voltages up to 5.5 V regardless of VCC level - including when powered from 3.3 V. This 5.5 V-tolerant input capability allows direct interfacing with 5 V peripherals without external level-shifting circuitry.

What is the function of the G (strobe) pin on the SN74LV157ADGVR?

The G pin is an active-low output strobe that globally enables or disables all four Y outputs. When G = low, outputs reflect the selected A/B data; when G = high, all Y outputs enter high-impedance state - enabling bus sharing and preventing signal contention in multi-driver systems.

Is the SN74LV157ADGVR pin-compatible with other 16-pin multiplexers like the SN74LS157?

No, the SN74LV157ADGVR is not pin-compatible with SN74LS157. While both are quadruple 2:1 multiplexers, the LV157A uses a different pinout: LS157 places G on pin 5 and separates A/B across pins 1 and 15, whereas SN74LV157ADGVR locates G on pin 15 and A/B on pin 1 - requiring PCB redesign for substitution.

What package type does the SN74LV157ADGVR use, and what are its dimensions?

The SN74LV157ADGVR uses a TVSOP-16 (DGV) package measuring 3.6 mm × 4.4 mm with 0.5 mm lead pitch and maximum height of 1.2 mm. Its small footprint and fine pitch make it ideal for high-density PCBs in space-constrained applications such as telecom modules and portable industrial controllers.
