NXP Semiconductors 74LV32PW,118

Overview

74LV32PW,118 from NXP Semiconductors is a low-voltage Si-gate CMOS quad 2-input OR gate, pin- and function-compatible with 74HC32 and 74HCT32, operating from 1.0 V to 5.5 V supply, delivering TTL-level input compatibility at 2.7–3.6 V, and specified for −40 °C to +125 °C industrial/automotive environments.

For engineers reviewing the 74LV32PW,118 datasheet, 74LV32PW,118 pinout, 74LV32PW,118 application, or 74LV32PW,118 equivalent, this page provides verified functional identity, TSSOP14 package mapping, propagation delay (6.0 ns typical at 3.3 V), output drive capability (±12 mA), ESD robustness (HBM >2000 V), and validated alternative options for logic-level translation and discrete gate replacement tasks.

Technical Context

The 74LV32PW,118 implements four independent 2-input OR gates in a single monolithic CMOS structure, with inputs tolerant of TTL voltage levels when VCC is between 2.7 V and 3.6 V. Its logic behavior follows standard positive-logic OR truth table: output is HIGH if either input is HIGH, LOW only when both inputs are LOW.

Designed for low-voltage mixed-signal systems, it supports rail-to-rail operation down to 1.0 V, exhibits low ground bounce (<0.8 V typical at 3.3 V), and maintains defined static characteristics across its full −40 °C to +125 °C temperature range without derating below 70 °C.

FAQ

What is the maximum operating supply voltage for the 74LV32PW,118?

The 74LV32PW,118 supports a maximum supply voltage of +5.5 V, with absolute maximum rating up to +7.0 V under limiting conditions. Operation above 5.5 V is not guaranteed and may cause permanent damage. The device is fully characterized from 1.0 V to 5.5 V, making it suitable for both legacy 5 V and modern low-voltage systems. Always observe recommended operating conditions in Table 5 of the NXP datasheet.

Is the 74LV32PW,118 pin-compatible with 74HC32 and 74HCT32?

Yes, the 74LV32PW,118 is explicitly stated as pin- and function-compatible with 74HC32 and 74HCT32. All three share identical pinout (14-pin TSSOP for PW variant), logic function (quad 2-input OR), and terminal assignments. However, the 74LV32PW,118 differs in supply range (1.0–5.5 V vs. 2.0–6.0 V for HC/HCT) and input threshold behavior - verify voltage translation requirements in mixed-supply designs.

Does the 74LV32PW,118 require external pull-up or pull-down resistors on unused inputs?

No, unused inputs on the 74LV32PW,118 must be tied to VCC or GND - floating inputs are prohibited due to CMOS susceptibility to noise-induced shoot-through current and potential latch-up. Each gate has two inputs; leaving either 1A or 1B unconnected risks undefined output state and increased ICC. Tie unused inputs directly to supply rails using short traces, not resistors, to minimize noise coupling.

What is the typical propagation delay of the 74LV32PW,118 at 3.3 V supply?

The typical propagation delay (tpd) of the 74LV32PW,118 is 6.0 ns when VCC = 3.3 V, CL = 15 pF, and Tamb = 25 °C, per Table 7 of the NXP datasheet. This value applies to both tPLH and tPHL transitions. At higher temperatures (+125 °C), maximum tpd increases to 13 ns under same conditions, ensuring timing predictability across full operating range.

Can the 74LV32PW,118 operate reliably at 1.2 V supply voltage?

Yes, the 74LV32PW,118 is fully specified and guaranteed to operate at 1.2 V supply, with static characteristics including VIH, VIL, VOH, and VOL validated down to this level. Propagation delay increases to 40 ns typical at 1.2 V (Table 7), and output drive reduces proportionally, but logic functionality remains intact. This makes it suitable for ultra-low-power applications such as energy-harvesting sensor nodes.
