Nexperia USA Inc. 74LVC1G38GM,132

Overview

74LVC1G38GM,132 from Nexperia is a single 2-input NAND gate with open-drain output, designed for level translation between 3.3 V and 5 V logic domains. It features Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and operates across 1.65 V to 5.5 V supply range. Used in I²C bus pull-up control, LED driver enable logic, and mixed-voltage interface conditioning.

For engineers reviewing the 74LVC1G38GM,132 datasheet, 74LVC1G38GM,132 pinout, 74LVC1G38GM,132 application, or 74LVC1G38GM,132 equivalent, this device is selected for low-power open-drain logic translation, high-noise-immunity input interfacing, and robust power-down isolation in space-constrained industrial and portable systems.

Technical Context

The 74LVC1G38GM implements standard NAND logic (Y = NOT(A AND B)) with an open-drain output requiring external pull-up. Its Schmitt-trigger inputs provide hysteresis (typ. 0.3 V at VCC = 3.3 V), enabling reliable operation with slow-rising signals like reset lines or mechanical switch inputs.

IOFF circuitry actively disables the output when VCC = 0 V, blocking backflow current up to ±50 mA - critical for hot-swap and multi-rail power sequencing. The device complies with JEDEC standards JESD8-7, JESD8-5, and JESD8-B/JESD36 across its full 1.65–5.5 V operating range.

FAQ

Can 74LVC1G38GM,132 drive a 5 V pull-up on the Y output while powered from 1.8 V?

Yes. The open-drain output is fully 5.5 V tolerant, and the internal FET can safely sink current when Y is pulled to 5 V, regardless of VCC (1.65–5.5 V). This enables true level translation without external components - confirmed by VI = 5.5 V tolerance and IO = ±24 mA rating at VCC = 3.0 V.

Does the 74LVC1G38GM,132 require external pull-up resistors on the Y output?

Yes. As an open-drain device, it lacks an internal pull-up; an external resistor (typically 1–10 kΩ) must connect Y to the desired logic-high voltage rail (e.g., 3.3 V or 5 V). The value is determined by rise time requirements and bus capacitance - no internal pull-up exists per functional diagram and pin description.

What is the purpose of the n.c. pin (Pin 5) in the SOT886 package?

Pin 5 is unconnected internally and serves no electrical function. It must remain unconnected - neither tied to GND nor routed - as confirmed in Table 3 (Pin Description) and Figure 8 (XSON6 pinning). Its presence accommodates standardized die pad layout but adds no functionality or thermal benefit.

How does IOFF protect the device during partial power-down?

When VCC = 0 V, the IOFF circuit disables the output FET, limiting leakage current to ±2 μA (per Table 7) and preventing backflow from live buses into the unpowered IC. This meets JEDEC JESD78 latch-up immunity requirements and avoids damage during hot-swap or staggered power sequencing - verified in Section 1 and Table 7.
