NXP Semiconductors 74LV132D,112

Overview

74LV132D,112 from Nexperia is a quad 2-input NAND gate with Schmitt-trigger inputs, designed for noise-immune signal conditioning in digital logic interfaces. It operates across 1.0 V to 5.5 V supply, features hysteresis (VH = 0.4–1.5 V), supports TTL-level inputs at VCC ≥ 2.7 V, and is rated for -40 °C to +125 °C operation in SO14 packaging. Used in wave shaping and multivibrator circuits where input noise rejection is critical.

For engineers reviewing the 74LV132D,112 datasheet, 74LV132D,112 pinout, 74LV132D,112 application, or 74LV132D,112 equivalent, key selection criteria include Schmitt-trigger hysteresis width, propagation delay (10 ns typical at 3.3 V), output drive capability (±12 mA), input clamp diode support for overvoltage-tolerant interfacing, and industrial temperature range compliance.

Technical Context

The 74LV132D implements four independent NAND gates, each with asymmetric Schmitt-trigger input thresholds (VT+ = 1.2–3.9 V, VT− = 0.6–2.6 V at VCC = 3.0–5.5 V) enabling robust noise margin in slow-rising or noisy signals. Its CMOS structure ensures low static current (≤40 μA at 5.5 V) and rail-to-rail output swing.

Input clamping diodes allow safe interface to voltages exceeding VCC when used with current-limiting resistors. The device complies with JEDEC standards JESD8-7 through JESD36 and meets HBM ESD >2000 V and CDM >1000 V per JS-001/JS-002.

Key Specifications

Pinout & Package

74LV132D,112 is housed in a plastic small outline package (SO14, SOT108-1) with 14 leads and 3.9 mm body width. Pin 1 is index-marked; the exposed pad is not electrically connected and may be left floating or tied to VCC if soldered.

FAQ

What is the minimum supply voltage at which 74LV132D,112 guarantees correct logic operation?

The device is guaranteed to function down to VCC = 1.0 V, with static characteristics fully specified from VCC = 1.2 V. At 1.0 V, operation is ensured when inputs are driven to GND or VCC levels-verified per datasheet Section 9's recommended operating conditions and Table 5 limits.

Can 74LV132D,112 inputs safely accept 5 V signals when powered from 3.3 V?

Yes. Integrated input clamp diodes allow safe interface to voltages exceeding VCC, provided external current-limiting resistors restrict IIK to ≤±20 mA (per Table 4). For 5 V inputs at 3.3 V VCC, a 100 Ω resistor limits current to ~17 mA, satisfying absolute maximum ratings.

How does the Schmitt-trigger hysteresis improve performance in noisy environments?

Hysteresis creates separate positive-going (VT+) and negative-going (VT−) input thresholds-e.g., 1.2 V and 0.6 V at VCC = 3.0 V-so noise spikes <0.6 V cannot falsely trigger state changes. This eliminates false toggling on slow or noisy edges, eliminating need for external RC filtering in applications like switch debouncing or sensor signal conditioning.

Is the exposed thermal pad on the SO14 package electrically connected?

No. Per datasheet Section 6.1, the exposed pad (Pin 14 reference note) is not a supply pin and has no electrical or mechanical requirement to be soldered. If soldered, it must remain electrically floating or be connected to VCC-not GND-to avoid violating internal biasing conditions.
