NXP Semiconductors 74LVC32APW/DG118

Overview

74LVC32APW/DG118 from Nexperia is a quad 2-input OR gate logic IC operating from 1.2 V to 3.6 V supply, featuring overvoltage-tolerant inputs (up to 5.5 V), Schmitt-trigger inputs for noise immunity, and guaranteed operation from −40 °C to +125 °C. It enables level translation between 3.3 V and 5 V domains in mixed-voltage digital interfaces.

For engineers reviewing the 74LVC32APW/DG118 datasheet, 74LVC32APW/DG118 pinout, 74LVC32APW/DG118 application, or 74LVC32APW/DG118 equivalent, key selection criteria include input voltage tolerance, propagation delay at 3.3 V (1.0–5.0 ns), output drive strength (±24 mA), thermal performance in TSSOP14, and JEDEC-compliant interface compatibility with TTL and LVTTL systems.

Technical Context

The 74LVC32APW/DG118 implements four independent OR gates in a single monolithic CMOS structure, each with Schmitt-trigger inputs enabling robust operation with slow-rising or noisy signals. Its input stage accepts voltages up to 5.5 V while powered from as low as 1.2 V, supporting bidirectional voltage translation without external components.

Designed for high-speed digital logic interfacing, it delivers sub-4 ns typical propagation delay at 3.3 V and maintains consistent timing across temperature (−40 °C to +125 °C) and supply (1.2 V–3.6 V). Output skew is limited to 1.5 ns, ensuring synchronized switching across all four gates under identical load conditions.

FAQ

What is the maximum input voltage the 74LVC32APW/DG118 can tolerate while powered at 1.8 V?

The 74LVC32APW/DG118 supports input voltages up to 5.5 V regardless of supply voltage - so at VCC = 1.8 V, inputs remain overvoltage-tolerant to 5.5 V. This enables safe interfacing with 5 V microcontrollers or sensors without external clamping diodes or level shifters, as confirmed in Table 4 (Limiting Values) and Section 1 of the datasheet.

Does the 74LVC32APW/DG118 require external pull-up resistors on its inputs?

No, the 74LVC32APW/DG118 does not require external pull-up resistors because it has no internal weak pull-ups. Inputs are high-impedance CMOS with Schmitt-trigger action, so unused inputs must be externally tied to VCC or GND to prevent floating states and unintended switching - a design requirement explicitly stated in Nexperia's application guidance for LVC logic.

Can the 74LVC32APW/DG118 operate reliably at 1.2 V supply voltage?

Yes, the 74LVC32APW/DG118 is fully specified down to 1.2 V supply voltage per Table 5 (Recommended Operating Conditions) and Table 6 (Static Characteristics). At 1.2 V, VIH is guaranteed ≥1.08 V and VOL ≤0.12 V, enabling interoperability with ultra-low-power processors and battery-monitoring circuits.

What is the thermal performance difference between the TSSOP14 and SO14 packages for the 74LVC32APW/DG118?

The TSSOP14 package (SOT402-1) used in 74LVC32APW/DG118 has a thermal derating slope of 7.3 mW/K above 81 °C, whereas the SO14 (SOT108-1) derates at 10.1 mW/K above 100 °C. This means the TSSOP version sustains higher power dissipation at elevated ambient temperatures - critical for compact industrial enclosures where airflow is restricted.

Is the 74LVC32APW/DG118 compliant with automotive AEC-Q100 standards?

No, the 74LVC32APW/DG118 is not AEC-Q100 qualified. Nexperia explicitly states in Section 14 (Legal Information) that unless a product data sheet expressly declares automotive qualification, the device is non-automotive. This part is rated for industrial temperature (−40 °C to +125 °C) but lacks stress testing, failure analysis, and documentation required for automotive use.
