Nexperia USA Inc. 74LV132BQ-Q100X

Overview

74LV132BQ-Q100 from Nexperia is an automotive-grade quad 2-input NAND Schmitt trigger IC in DHVQFN14 package, operating from 1.0 V to 5.5 V supply, delivering input hysteresis (VH = 0.4–1.5 V) and propagation delay as low as 9.0 ns at 5.0 V. It transforms slow/noisy inputs into clean digital outputs and is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C) for engine control, body electronics, and ADAS sensor interface circuits.

For engineers reviewing the 74LV132BQ-Q100 datasheet, 74LV132BQ-Q100 pinout, 74LV132BQ-Q100 application, or 74LV132BQ-Q100 equivalent, key selection criteria include Schmitt-trigger hysteresis voltage (VT+ / VT−), propagation delay across 1.2–5.5 V supply range, output drive capability (±25 mA), ESD robustness (HBM >2000 V), and thermal-enhanced DHVQFN14 package compatibility with AOI inspection.

Technical Context

This device implements four independent 2-input NAND gates with Schmitt-trigger inputs, each exhibiting asymmetric switching thresholds (VT+ and VT−) to provide noise immunity and eliminate chatter on slow-rising/falling signals. Its CMOS Si-gate architecture ensures TTL-level compatibility at VCC = 2.7–3.6 V and supports rail-to-rail input/output swing.

The logic function follows standard NAND truth table (L/L→H, L/H→H, H/L→H, H/H→L), with hysteresis defined as VH = VT+ − VT−, ranging from 0.3 V (1.2 V supply) to 1.5 V (5.5 V supply). Input leakage remains ≤1.0 μA at 5.5 V, and dynamic power dissipation is characterized by CPD = 24 pF.

FAQ

Can 74LV132BQ-Q100 operate reliably at 1.0 V supply?

Yes - the device is fully specified down to 1.0 V supply per Table 5, with guaranteed functionality (though static parameters like VOH/VOL are characterized from 1.2 V). At 1.0 V, propagation delay increases (e.g., 65 ns at VCC = 1.2 V), and input hysteresis reduces (~0.3 V), but logic operation remains valid for ultra-low-power wake-up circuits.

Is the exposed thermal pad on Pin 1 of DHVQFN14 electrically connected?

No - the exposed pad (terminal 1 index area) is not electrically connected to any internal node. Per datasheet Section 6.1, it may remain floating or be connected to VCC, but must never be tied to GND or left unconnected with solder paste bridging to adjacent terminals.

How does the hysteresis voltage (VH) vary with supply voltage?

VH scales with VCC: it is 0.3 V (min) at 1.2 V, 0.4–0.8 V at 2.0–3.0 V, and 0.6–1.5 V at 4.5–5.5 V (Table 10). This ensures consistent noise margin percentage-wise across supply rails - e.g., ~25 % of VCC at 3.3 V (VH ≈ 0.8 V) and ~27 % at 5.5 V (VH ≈ 1.5 V).

What is the maximum capacitive load this device can drive while maintaining specified tpd?

The 10 ns typical propagation delay at VCC = 3.3 V assumes CL = 15 pF (Table 7). Driving >50 pF increases tpd nonlinearly and may cause excessive rise/fall times; for loads >30 pF, add series termination or buffer stages. The CPD = 24 pF value indicates inherent switching capacitance, not drive capability limit.
