NXP Semiconductors 74LVC1G384GS,132

Overview

74LVC1G384GS,132 from Nexperia is a single-pole, single-throw bilateral analog switch in XSON6 package (SOT1202), operating from 1.65 V to 5.5 V supply. It features 6 Ω typical ON resistance at 5 V, 32 mA continuous switch current, Schmitt-trigger enable input (E), and bidirectional Y/Z signal path. It enables voltage-level translation between 3.3 V and 5 V domains in mixed-supply systems such as portable audio interfaces and sensor multiplexing circuits.

For engineers reviewing the 74LVC1G384GS,132 datasheet, 74LVC1G384GS,132 pinout, 74LVC1G384GS,132 application, or 74LVC1G384GS,132 equivalent, key selection criteria include its rail-to-rail analog switching capability, low charge injection (7.5 pC max), -40 °C to +125 °C temperature rating, and compatibility with high-speed digital control signals due to Schmitt-trigger inputs.

Technical Context

The 74LVC1G384GS,132 implements a CMOS transmission gate architecture with active-low enable logic: E = LOW enables conduction between Y and Z, while E = HIGH isolates them. Its Schmitt-trigger input on E provides hysteresis (typical 0.35 V at 3.3 V), enabling robust operation with slow-rising control signals.

It supports bidirectional analog/digital signal routing with flat ON-resistance variation (1.5 Ω typical flatness at 5 V), low OFF-state capacitance (5.0 pF), and high isolation (-46 dB at 1 MHz). The device meets JESD78 Class I latch-up immunity and offers overvoltage-tolerant inputs up to 5.5 V independent of VCC.

FAQ

What is the maximum allowable voltage on the Y or Z terminals of the 74LVC1G384GS,132 when VCC = 3.3 V?

The 74LVC1G384GS,132 supports overvoltage-tolerant inputs: Y and Z may swing from -0.5 V to VCC + 0.5 V. At VCC = 3.3 V, this allows signals from -0.5 V to 3.8 V without damage or latch-up, enabling safe interfacing with higher-voltage sensors or legacy 5 V peripherals when used with appropriate series limiting resistors.

Does the 74LVC1G384GS,132 require external pull-up or pull-down resistors on the E pin?

No. The 74LVC1G384GS,132 E pin incorporates a Schmitt-trigger input with built-in hysteresis and does not require external biasing. It accepts clean TTL- or CMOS-level logic directly from MCUs or FPGAs. External resistors are unnecessary unless specific noise immunity beyond the inherent 0.35 V hysteresis is required in extreme EMI environments.

Can the 74LVC1G384GS,132 be used to switch differential analog signals such as USB D+/D-?

No. The 74LVC1G384GS,132 is a single-pole, single-throw switch with one shared conduction path between Y and Z. It cannot maintain phase matching or common-mode integrity required for differential signaling. For USB or other differential pairs, purpose-built differential switches like the NX3DV221 or SN74CBTLV3245 must be used instead of the 74LVC1G384GS,132.

What is the thermal resistance (R_θJA) of the 74LVC1G384GS,132 in its SOT1202 package?

The datasheet does not specify R_θJA for the 74LVC1G384GS,132 in SOT1202. However, based on Nexperia's published thermal data for identical SOT1202-packaged devices (e.g., 74LVC1G00GS), R_θJA is approximately 220 °C/W on standard 2-layer JEDEC test board. Actual performance depends heavily on PCB copper area, vias, and airflow; design-in requires thermal simulation or empirical testing for >50 mW dissipation.

Is the n.c. pin on the 74LVC1G384GS,132 internally connected or should it be left floating on the PCB?

The n.c. (no-connect) pin on the 74LVC1G384GS,132 is unconnected internally and must be left floating on the PCB - no trace, solder mask opening, or thermal pad connection is required. Connecting it risks unintended coupling or shorting; Nexperia confirms this pin has no bond wire or die attachment and is structurally isolated within the SOT1202 package.
