NXP Semiconductors 74LV32D,118

Overview

74LV32D,118 from NXP Semiconductors is a low-voltage Si-gate CMOS quad 2-input OR gate, pin- and function-compatible with 74HC32 and 74HCT32. It operates from 1.0 V to 5.5 V, delivers propagation delays as low as 6.0 ns at 3.3 V/15 pF, supports −40 °C to +125 °C ambient range, and is packaged in SO14 (SOT108-1) for surface-mount logic integration in power-constrained industrial control systems.

For engineers reviewing the 74LV32D,118 datasheet, 74LV32D,118 pinout, 74LV32D,118 application, or 74LV32D,118 equivalent, key selection criteria include its wide 1.0–5.5 V supply range, TTL-level input compatibility at 2.7–3.6 V, guaranteed operation down to 1.0 V, low ground bounce (<0.8 V), and thermal stability across automotive-grade temperature extremes.

Technical Context

The 74LV32D,118 implements four independent OR logic gates using silicon-gate CMOS technology optimized for low-voltage operation. Its input structure accepts TTL-level signals when VCC is between 2.7 V and 3.6 V, and its output drive capability supports ±12 mA at 4.5 V while maintaining VOL ≤ 0.55 V and VOH ≥ 3.5 V under load.

Designed for noise-resilient digital interfacing, it features ESD protection exceeding 2000 V HBM and 200 V MM, and exhibits controlled dynamic behavior with CPD = 16 pF - enabling accurate power estimation via PD = CPD × VCC² × fi × N + Σ(CL × VCC² × fo).

FAQ

What is the minimum supply voltage at which 74LV32D,118 guarantees correct logic operation?

The 74LV32D,118 guarantees functional operation down to 1.0 V, with static characteristics specified from 1.2 V to 5.5 V. At VCC = 1.0 V, the device functions correctly when inputs are driven to GND or VCC, satisfying core OR logic truth table behavior - verified across the full −40 °C to +125 °C temperature range per NXP's 2007 product data sheet Rev. 03.

Does 74LV32D,118 support TTL-level input signals, and under what conditions?

Yes, 74LV32D,118 accepts TTL input levels when VCC is between 2.7 V and 3.6 V. Within this range, VIH(min) = 2.0 V and VIL(max) = 0.8 V meet standard TTL thresholds, allowing direct connection to 5 V TTL outputs without level-shifting circuitry - a feature explicitly confirmed in Section 2 of the NXP datasheet.

What is the maximum output current drive capability of 74LV32D,118 at 3.3 V supply?

At VCC = 3.0 V, the 74LV32D,118 delivers VOH ≥ 2.2 V at IO = −6 mA (sink) and VOL ≤ 0.40 V at IO = 6 mA (source), per Table 6 Static Characteristics. This confirms usable drive strength for interfacing with multiple 74LVC inputs or moderate capacitive loads in 3.3 V systems.

Is 74LV32D,118 pin-compatible with 74HC32 and 74HCT32, and does it share the same SO14 footprint?

Yes, the 74LV32D,118 is pin- and function-compatible with both 74HC32 and 74HCT32, and uses the identical SO14 (SOT108-1) package with 14 leads and 1.27 mm pitch - as documented in Table 1 Ordering Information and Figure 4 Pin Configuration. No PCB redesign is needed when upgrading from HC/HCT to LV in existing SO14 layouts.

What thermal derating applies to 74LV32D,118 in SO14 package above 70 °C?

For the SO14 package (SOT108-1), total power dissipation (Ptot) derates linearly at 8 mW/K above 70 °C, with a maximum rating of 500 mW at Tamb ≤ 70 °C. This derating slope is defined in Table 4 Limiting Values and ensures safe operation up to the +125 °C maximum ambient temperature.
