NXP Semiconductors 74LV32N,112

Overview

74LV32N,112 from NXP Semiconductors is a low-voltage Si-gate CMOS quad 2-input OR gate in a 14-lead DIP package, operating from 1.0 V to 5.5 V supply, with −40 °C to +125 °C temperature range, TTL-level input compatibility at 2.7–3.6 V, and propagation delay as low as 6.0 ns at 3.3 V/15 pF.

For engineers reviewing the 74LV32N,112 datasheet, 74LV32N,112 pinout, 74LV32N,112 application, or 74LV32N,112 equivalent, this device serves as a drop-in logic replacement for 74HC32/74HCT32 in industrial control, power management sequencing, and legacy TTL-to-CMOS interface designs where wide V_CC range and robust ESD protection (HBM >2000 V) are required.

Technical Context

The 74LV32N,112 implements four independent OR gates using standard CMOS logic architecture, with each gate accepting two inputs and producing one active-high output. Its input thresholds are adaptive across V_CC: VIH = 2.0 V (min) at 2.7–3.6 V, and VIL = 0.8 V (max) under same conditions.

It supports mixed-voltage interfacing via TTL-compatible inputs when V_CC = 2.7–3.6 V and delivers rail-to-rail output swing - VOH ≥ 2.82 V (at I_O = −6 mA, V_CC = 3.0 V) and VOL ≤ 0.40 V (at I_O = 6 mA, V_CC = 3.0 V) - enabling reliable signal integrity in noise-sensitive digital subsystems.

FAQ

What is the maximum propagation delay of the 74LV32N,112 at 3.3 V?

The 74LV32N,112 has a maximum propagation delay of 13 ns at V_CC = 3.0–3.6 V and C_L = 15 pF, as specified in Table 7 of the NXP datasheet Rev. 03. This value applies across the full −40 °C to +125 °C operating range and ensures timing margin for synchronous logic design in industrial control applications using the 74LV32N,112.

Can the 74LV32N,112 accept 5 V TTL inputs while powered at 3.3 V?

Yes, the 74LV32N,112 accepts TTL input levels when V_CC is between 2.7 V and 3.6 V, per Section 2 of the datasheet. At V_CC = 3.3 V, VIH(min) = 2.0 V and VIL(max) = 0.8 V, fully accommodating standard 5 V TTL output swings (2.4 V HIGH, 0.4 V LOW). This feature eliminates external level shifters in mixed-voltage systems using the 74LV32N,112.

Is the 74LV32N,112 pin-compatible with the 74HC32 and 74HCT32?

Yes, the 74LV32N,112 is explicitly stated in the General Description to be pin and function compatible with both 74HC32 and 74HCT32. Pin numbering, logic function per gate, and package outline (DIP14) match identically, enabling direct replacement in existing designs without PCB modification - a key advantage confirmed for the 74LV32N,112 in legacy system upgrades.

What is the thermal derating behavior of the 74LV32N,112 in DIP14 package?

The 74LV32N,112 in DIP14 (SOT27-1) package has a total power dissipation limit of 750 mW at Tamb ≤ 70 °C, derating linearly by 12 mW/K above that temperature, per Table 4. This allows safe operation up to +125 °C ambient if total power remains below ~75 mW at maximum temperature - critical for thermally constrained industrial enclosures where the 74LV32N,112 is deployed.

Does the 74LV32N,112 support operation at 1.2 V supply?

Yes, the 74LV32N,112 is fully specified down to 1.0 V supply, with static characteristics guaranteed from V_CC = 1.2 V and functional operation confirmed to 1.0 V (with inputs at GND or V_CC), per Table 5 footnote [1]. This makes the 74LV32N,112 suitable for ultra-low-power battery-operated devices where supply rails dip to 1.2 V during discharge cycles.
