NXP Semiconductors 74LV32PW,112

Overview

74LV32PW,112 from NXP Semiconductors is a low-voltage Si-gate CMOS quad 2-input OR gate operating from 1.0 V to 5.5 V supply, delivering propagation delays as low as 6.0 ns at VCC = 3.3 V and CL = 15 pF, with TTL-level input compatibility at 2.7–3.6 V, used in logic-level translation and discrete combinational logic blocks within industrial control I/O modules.

For engineers reviewing the 74LV32PW,112 datasheet, 74LV32PW,112 pinout, 74LV32PW,112 application, or 74LV32PW,112 equivalent, key selection criteria include its −40 °C to +125 °C temperature rating, TSSOP14 package footprint, guaranteed operation down to 1.0 V, ground bounce < 0.8 V at 3.3 V, and compatibility with 74HC32/74HCT32 designs requiring low-voltage logic interfacing.

Technical Context

The 74LV32PW,112 implements four independent OR gates using standard CMOS logic architecture, with each gate accepting two inputs (nA, nB) and producing one output (nY) per truth table: H/X→H, X/H→H, L/L→L. Input thresholds are adaptive across VCC - VIH = 2.0 V (min) at 2.7–3.6 V, VIL = 0.8 V (max) in same range - enabling robust noise margin in mixed-supply systems.

Dynamic performance is characterized by symmetric tPLH/tPHL propagation delays, load-dependent timing (CL = 15 pF typical test condition), and CPD = 16 pF for dynamic power estimation. The device supports high-speed switching up to 100 ns/V input transition rate at VCC ≥ 3.6 V, with static ICC ≤ 40 µA at 5.5 V and input leakage ≤ 1.0 µA.

FAQ

What is the minimum supply voltage for reliable operation of the 74LV32PW,112?

The 74LV32PW,112 is guaranteed to function down to VCC = 1.0 V with input levels referenced to GND or VCC, as confirmed in Table 5 (Recommended Operating Conditions) of the NXP datasheet. Static characteristics are specified from 1.2 V, but functional operation is validated at 1.0 V - critical for battery-powered or cold-crank automotive applications where supply may dip below nominal rails. This capability is intrinsic to the LV family design and applies specifically to the 74LV32PW,112.

Does the 74LV32PW,112 support TTL-level inputs, and under what conditions?

Yes, the 74LV32PW,112 accepts TTL input levels (VIH ≥ 2.0 V, VIL ≤ 0.8 V) when VCC is between 2.7 V and 3.6 V, as explicitly stated in Section 2 (Features) and Table 6 (Static Characteristics) of the datasheet. This allows direct connection to 74LS, 74F, or microcontroller GPIOs operating at 3.3 V without external level shifting. Outside this VCC range, input thresholds scale with VCC and do not maintain TTL compatibility. This behavior is confirmed for the exact 74LV32PW,112 variant.

What is the thermal performance of the 74LV32PW,112 in its TSSOP14 package?

The 74LV32PW,112 in TSSOP14 (SOT402-1) has a maximum total power dissipation of 500 mW at Tamb = −40 °C to +125 °C, with linear derating of 5.5 mW/K above +60 °C (Table 4, Limiting Values). Its compact 4.4 mm × 5.1 mm footprint provides lower thermal resistance than DIP or SOIC variants, enabling higher ambient operation in confined spaces. This thermal rating is specific to the 74LV32PW,112 package configuration and verified per NXP's characterization data.

Is the 74LV32PW,112 pin-compatible with the 74HC32 and 74HCT32?

Yes, the 74LV32PW,112 is pin and function compatible with both 74HC32 and 74HCT32, as stated in the General Description section of the NXP datasheet. All three devices share identical pin assignments (1A–4Y, GND, VCC), truth table behavior, and functional OR gate implementation. However, the 74LV32PW,112 extends voltage range down to 1.0 V and adds TTL input compatibility at 2.7–3.6 V - enhancements beyond the HC/HCT families. This compatibility applies directly to the 74LV32PW,112.

What are the ESD protection ratings for the 74LV32PW,112, and how are they tested?

The 74LV32PW,112 features Human Body Model (HBM) ESD protection exceeding 2000 V and Machine Model (MM) protection exceeding 200 V, per JESD22-A114E and JESD22-A115-A standards respectively (Section 2, Features). These ratings are measured on all pins relative to GND and VCC, and reflect the device's robustness during handling and board assembly. No external protection components are required for standard manufacturing environments. This specification is confirmed for the 74LV32PW,112 in its TSSOP14 package.
