Nexperia USA Inc. 74LVC1G157GS,132

Overview

74LVC1G157GS,132 from Nexperia is a single 2-input CMOS multiplexer with Schmitt-trigger inputs, IOFF partial power-down protection, and dual-voltage translation capability (1.65 V to 5.5 V supply). It selects between two data sources (I0/I1) using a common select input (S), delivering the chosen signal to output Y. Used in level-shifting I/O interfaces, bus arbitration, and signal routing in space-constrained industrial controllers and portable electronics.

For engineers reviewing the 74LVC1G157GS,132 datasheet, 74LVC1G157GS,132 pinout, 74LVC1G157GS,132 application, or 74LVC1G157GS,132 equivalent, key selection criteria include its 6-terminal XSON6 package (SOT1202), ±24 mA drive at 3.0 V, IOFF-enabled hot-swap compatibility, and guaranteed operation from –40 °C to +125 °C.

Technical Context

This device implements a single-pole double-throw (SPDT) analog/digital signal switch via complementary MOS logic, with independent Schmitt-trigger hysteresis on all inputs (I0, I1, S) to tolerate slow-rising signals and suppress noise-induced glitches. Its IOFF circuit actively disables output Y when VCC = 0 V, blocking backflow current during partial power-down sequences.

The logic function is strictly combinatorial: Y = (S̅ · I0) + (S · I1), with propagation delays as low as 0.5 ns at 5.5 V and load-dependent timing validated per JEDEC JESD8 standards across 1.65–5.5 V supply range. No internal latching, clocking, or state retention is present.

FAQ

Can 74LVC1G157GS,132 operate with VCC = 1.8 V while accepting 3.3 V inputs?

Yes. The device supports overvoltage-tolerant inputs up to 5.5 V independent of VCC. At VCC = 1.8 V, VIH is 0.65 × VCC = 1.17 V and VIL is 0.35 × VCC = 0.63 V, ensuring reliable recognition of 3.3 V logic HIGH/LOW levels without damage or level-shifting circuitry.

Does the IOFF feature require external pull-down resistors on Y when VCC = 0 V?

No. The internal IOFF circuit actively disables the output stage and presents high-impedance on Y when VCC = 0 V, eliminating the need for external resistors. Output leakage remains ≤±2 μA, preventing unintended loading of downstream circuits during power-down.

What is the maximum capacitive load the Y output can drive at 10 MHz with VCC = 3.3 V?

At 10 MHz and VCC = 3.3 V, the output can reliably drive up to 50 pF (including trace and probe capacitance) while maintaining tPLH/tPHL ≤ 6.3 ns and VOL ≤ 0.55 V at 24 mA sink. Exceeding 50 pF increases propagation delay and may cause timing violations in synchronous systems.

Is the SOT1202 package compatible with standard XSON6 reflow profiles?

Yes. SOT1202 (XSON6) follows JEDEC J-STD-020D moisture sensitivity level 1 (MSL1) and is qualified for peak reflow temperatures up to 260 °C. Standard lead-free reflow profiles with 60–90 s above 217 °C are fully supported; no special stencil or placement adjustments are needed beyond standard XSON6 guidelines.
