Product details

Overview

MC74HC1G32DFT1G-L22038 from onsemi is a single 2-input OR gate in SC-88A (SOT-353) package, fabricated with silicon gate CMOS technology. It delivers high-speed operation (t_PD = 7 ns typ at V_CC = 5 V), symmetrical output drive (I_OH/I_OL = ±2 mA), and operates across −55°C to +125°C for industrial and automotive signal logic applications.

For engineers reviewing the MC74HC1G32DFT1G-L22038 datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated SC-88A pin mapping, confirmed AEC-Q100 qualification status, and real-world logic-level translation use cases - all directly traceable to onsemi's official Rev. 20 datasheet.

Technical Context

The MC74HC1G32DFT1G-L22038 implements a single 2-input positive-logic OR function with buffered output stage, ensuring high noise immunity and stable switching. Its internal architecture uses <100 FETs and features balanced propagation delays (t_PLH ≈ t_PHL) and symmetrical output impedance (|I_OH| = |I_OL| = 2 mA).

It supports wide V_CC range (2.0–6.0 V), meets AEC-Q100 Grade 1 requirements (−40°C to +125°C ambient), and exhibits robust ESD tolerance (2000 V HBM). Input thresholds scale with supply voltage (VIH = 0.7×V_CC, VIL = 0.3×V_CC), enabling reliable interfacing across mixed-voltage logic domains.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	2.0 V to 6.0 V - enables direct interface with 3.3 V and 5 V logic systems without level shifters
t_PD (Typ)	7 ns at V_CC = 5 V, C_L = 15 pF - supports >100 MHz toggle rates in low-load digital paths
I_OH/I_OL	±2 mA - sufficient to drive one 74HC input or small capacitive loads (<30 pF) without buffering
Operating Temp	−55°C to +125°C - qualified for under-hood automotive and extended industrial environments
ESD Rating	2000 V HBM - exceeds IEC 61000-4-2 Level 2 for board-level handling robustness
Input Leakage	≤1.0 μA max at V_IN = 6.0 V - ensures minimal current draw in battery-backed or sleep-mode circuits
Quiescent ICC	≤40 μA max at V_CC = 6.0 V - supports ultra-low-power standby states in portable systems

Pinout & Package

MC74HC1G32DFT1G-L22038 is housed in a 5-pin SC-88A (SOT-353) surface-mount package measuring 2.0 mm × 1.25 mm × 0.95 mm, with gull-wing leads and moisture sensitivity level (MSL) 1.

Pin/Terminal	Circuit Role	Design Meaning
1	Input A	Primary OR operand input; accepts standard CMOS logic levels referenced to V_CC
2	Input B	Secondary OR operand input; electrically identical to Pin 1, fully interchangeable
3	GND	Dedicated ground reference for logic threshold and output sink path; must be low-impedance
4	V_CC	Positive supply rail; decoupling capacitor (0.1 μF) required within 5 mm for stable AC performance
5	Output Y	OR result (Y = A + B); push-pull CMOS output capable of sourcing/sinking ±2 mA

Key Features

Feature	Design Value
High-speed propagation	7 ns typical delay at 5 V enables timing-critical combinational logic in microcontroller peripheral interfaces
Supply voltage flexibility	2.0–6.0 V operation allows seamless integration into mixed-rail systems (e.g., 3.3 V MCU + 5 V sensor interface)
Automotive qualification	AEC-Q100 Grade 1 compliance ensures reliability in automotive body control modules and infotainment power sequencing
Low dynamic power	CPD = 10 pF enables sub-μW dynamic consumption at 100 kHz clocking - critical for always-on wake-up logic
Pb-free & RoHS	Halogen-free/BFR-free construction meets IPC-J-STD-609 Class 1 and EU RoHS Directive 2011/65/EU

Equivalent & Alternatives

The following parts are listed as comparable options for similar 2-input OR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G32DBVR	Lower V_CC min (1.65 V), faster t_PD (3.7 ns @ 3.3 V), but only rated to +85°C	Not qualified for automotive or extended-temp industrial use; lacks AEC-Q100 certification	Select when operating exclusively at 1.8–3.3 V and ambient ≤85°C; avoid for under-hood or outdoor deployments
74AUP1G32GW,125	Ultra-low ICC (0.9 μA max), wider V_CC (0.8–3.6 V), but limited I_OH/I_OL (±1 mA)	Optimized for battery-powered IoT nodes; insufficient drive for HC-family fanout or 5 V systems	Prefer for energy-constrained edge devices where speed <5 ns is unnecessary and 5 V compatibility is not required

Compared with SN74LVC1G32DBVR and 74AUP1G32GW,125, the MC74HC1G32DFT1G-L22038 uniquely balances wide temperature range (−55°C to +125°C), 2–6 V supply flexibility, and AEC-Q100 qualification - making it the only choice for automotive power sequencing and industrial sensor fusion where reliability across thermal extremes is non-negotiable.

The MC74HC1G32DFT1G-L22038 is rated for operation from −55°C to +125°C, meeting AEC-Q100 Grade 1 requirements. This specification is validated per onsemi's official datasheet Rev. 20 and applies to the SC-88A packaged MC74HC1G32DFT1G-L22038 across its full recommended V_CC range (2.0–6.0 V). Thermal derating is not required up to +125°C ambient.

Does MC74HC1G32DFT1G-L22038 support 3.3 V logic systems?

Yes, MC74HC1G32DFT1G-L22038 fully supports 3.3 V logic systems. Its recommended V_CC range includes 3.0–3.6 V, with VIH = 2.1 V (min) and VIL = 0.9 V (max) at V_CC = 3.0 V. The device delivers t_PD = 8 ns (typ) and I_OH/I_OL = ±2 mA under these conditions, ensuring robust interoperability with standard 3.3 V CMOS and LVTTL interfaces.

Is MC74HC1G32DFT1G-L22038 pin-compatible with other SC-88A 5-pin logic gates?

No - MC74HC1G32DFT1G-L22038 has a fixed pinout (1:A, 2:B, 3:GND, 4:V_CC, 5:Y) defined in onsemi's datasheet Figure 1. While other SC-88A logic gates share the same package footprint, their pin assignments differ (e.g., inverters place V_CC on Pin 5). PCB layout must follow the exact MC74HC1G32DFT1G-L22038 pin map; substitution requires schematic and layout verification.

What is the ESD rating of MC74HC1G32DFT1G-L22038?

The MC74HC1G32DFT1G-L22038 has an ESD withstand voltage of 2000 V per Human Body Model (HBM), as tested to ANSI/ESDA/JEDEC JS-001-2017. This rating is specified in the "Maximum Ratings" table of onsemi's official datasheet and reflects device-level robustness during handling and assembly - no external protection diodes are required for standard PCB handling per J-STD-001.
