74HCT32DB,118

Inverter Gates Overview

The Nexperia 74HCT32DB,118 is a quad 2-input OR gate belonging to the HCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an ambient temperature range from -40 °C to +125 °C. The device features TTL-compatible input levels and CMOS low power dissipation. It is housed in a 14-lead SO plastic small outline package (SOT108-1) with a body width of 3.9 mm. Static characteristics include high-level output voltages up to 4.4 V at -20 μA load and low-level output voltages down to 0.1 V at 20 μA load. Dynamic performance specifies propagation delays of 24 ns maximum at 4.5 V and 36 ns maximum at 5.5 V under 50 pF load conditions.

Inverter Gates Feature Summary

• Provides four independent 2-input OR logic functions within a single integrated circuit
• Ensures high noise immunity and symmetrical output impedance for reliable signal processing
• Incorporates input clamp diodes to facilitate interfacing with voltages exceeding the supply rail
• Delivers balanced propagation delays and complies with JEDEC standards for robust latch-up performance

Inverter Gates Applications

• General purpose digital logic implementation
• Signal routing and selection circuits
• Control logic for embedded systems

Inverter Gates Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the DB designation corresponds to the SO14 form factor. Confirm that the procurement channel sources products directly from Nexperia or authorized distributors to ensure authenticity. Check for any recent product change notifications regarding marking or assembly updates. Ensure storage and handling procedures comply with moisture sensitivity level requirements prior to soldering.

Inverter Gates Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS low power consumption characteristics. The wide operating temperature range makes it suitable for industrial environments. Consider the 14-lead SO package dimensions for PCB layout constraints. Verify that the supply voltage remains strictly within the 4.5 V to 5.5 V limits to maintain specified electrical parameters and prevent device damage.

Inverter Gates Part Context

This part belongs to the 74HCT32 series, which defines the functional behavior of quad 2-input OR gates. The 'DB' suffix specifically identifies the physical packaging as a 14-lead Small Outline Package (SO). The '118' suffix denotes the standard tape and reel packaging configuration used for automated surface-mount assembly processes.
