Product details
Overview
SN74LVC1G132DBVTG4 from Texas Instruments is a single 2-input NAND gate with Schmitt-trigger inputs, designed for noise-immune digital signal conditioning in low-voltage systems. It operates from 1.65V to 5.5V, delivers ±24mA output drive at 3.3V, achieves 5.3ns max propagation delay, and supports partial-power-down via Ioff. It is used in portable audio interfaces and tamper-detection circuits where slow or noisy input edges must be reliably interpreted.
For engineers reviewing the SN74LVC1G132DBVTG4 datasheet, SN74LVC1G132DBVTG4 pinout, SN74LVC1G132DBVTG4 application, or SN74LVC1G132DBVTG4 equivalent, key selection criteria include Schmitt-trigger hysteresis (ΔVT = 0.71V min at 4.5V), over-voltage tolerant inputs (up to 5.5V), latch-up immunity (>100mA), and SOT-23-5 package compatibility with space-constrained PCB layouts.
Technical Context
This device implements positive-logic NAND functionality (Y = A • B) using balanced CMOS push-pull outputs and Schmitt-trigger input circuitry. Its hysteresis (ΔVT) enables robust operation with slow-rising signals and noise margins up to ±0.355V at 4.5V supply, eliminating need for external RC filtering.
The Ioff feature disables all outputs when VCC = 0V, limiting leakage to ±10µA and enabling hot-insertion in multi-rail systems. Input voltage tolerance extends to 5.5V independent of VCC, allowing interfacing with higher-voltage logic without level shifters.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate with Schmitt-trigger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G132DBVR | Same silicon, tape-and-reel packaging (3000 pcs/reel); identical electrical specs and pinout | No functional difference; selected for automated SMT assembly vs. sample evaluation | Choose DBVR for volume production; DBVTG4 is cut-tape variant optimized for prototyping and low-volume builds |
| NC7SZ132P5X | Lower drive (±24mA only at 4.5V), wider tpd range (6.5ns max at 3.3V), different hysteresis profile (ΔVT = 0.5V typ at 3.3V) | Less noise margin in 3.3V systems; requires tighter layout control for same reliability | Use NC7SZ132P5X only if legacy design uses ON Semiconductor footprint and timing budget allows +1.2ns delay margin |
Compared with SN74LVC1G132DBVTG4, SN74LVC1G132DBVR offers identical performance in volume packaging, while NC7SZ132P5X trades hysteresis and drive strength for broader vendor availability - making DBVTG4 optimal for new designs requiring maximum noise immunity and consistent 3.3V timing.

FAQ
What is the maximum input voltage rating for SN74LVC1G132DBVTG4?
The SN74LVC1G132DBVTG4 supports input voltages up to 5.5V on pins A and B, regardless of the VCC supply level. This over-voltage tolerance allows direct interfacing with 5V logic signals even when operating from a 1.8V or 2.5V rail - a key advantage over standard CMOS gates that require level translation.
Does SN74LVC1G132DBVTG4 support partial-power-down mode?
Yes, SN74LVC1G132DBVTG4 includes Ioff circuitry that disables all outputs and limits leakage current to ±10µA when VCC = 0V. This feature enables safe hot-insertion in multi-rail systems and supports power-gating strategies in battery-operated devices without risking backfeeding or latch-up.
What is the typical hysteresis (ΔVT) of SN74LVC1G132DBVTG4 at 3.3V supply?
At 3.3V supply, the SN74LVC1G132DBVTG4 exhibits a minimum hysteresis (ΔVT) of 0.56V, with typical value of 0.87V. This wide input threshold separation ensures reliable switching in the presence of noise up to 560mV peak-to-peak, making it ideal for mechanical switch debouncing and EMI-prone environments.
Can SN74LVC1G132DBVTG4 drive an LED directly?
Yes, SN74LVC1G132DBVTG4 can drive a standard 20mA LED directly when configured as an active-low sink (Y → LED anode → VCC; LED cathode → Y). Its 24mA sink capability at 3.3V and VOL ≤ 0.55V ensure sufficient margin for red/green/yellow LEDs with 150–330Ω current-limiting resistors.
What package type is used for SN74LVC1G132DBVTG4?
SN74LVC1G132DBVTG4 uses the DBV package: a 5-pin SOT-23 variant measuring 2.9mm × 2.8mm with 1.6mm body width. It is RoHS-compliant, lead-free, and compatible with standard reflow soldering profiles - widely adopted in space-constrained portable electronics.
