Product details

Overview

CLVC1G32MDCKREPG4 from Texas Instruments is a single 2-input positive-OR gate logic IC designed for 1.65-V to 5.5-V V_CC operation, featuring I_off support for partial power-down mode, ±24-mA output drive at 3.3 V, and max propagation delay of 3.6 ns at 3.3 V. It serves as a level-shifting combinational logic element in low-voltage interface circuits, battery-powered sensors, and industrial control signal conditioning.

For engineers reviewing the CLVC1G32MDCKREPG4 datasheet, CLVC1G32MDCKREPG4 pinout, CLVC1G32MDCKREPG4 application, or CLVC1G32MDCKREPG4 equivalent, key selection criteria include its extended temperature range (–55°C to 125°C), 5-pin SC-70 (DCK) package, I_off current limiting, and 5.5-V tolerant inputs - critical for mixed-voltage system interoperability and robustness in harsh environments.

Technical Context

This device implements Boolean OR logic (Y = A + B) in positive logic using LVC-series CMOS technology, with rail-to-rail input voltage tolerance up to 5.5 V independent of V_CC. Its I_off circuitry actively disables outputs during power-down, preventing backflow current into powered sections of the system.

It operates across 1.65 V–5.5 V supply range with guaranteed switching performance down to 1.65 V, supports 15-pF load-driven t_pd ≤ 3.6 ns at 3.3 V, and maintains latch-up immunity exceeding 100 mA per JESD 78 Class II - enabling use in hot-swap and multi-rail embedded subsystems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 5.5 V - enables direct interfacing between 1.8-V, 2.5-V, 3.3-V, and 5-V logic domains without level shifters.
Max t_pd	3.6 ns at V_CC = 3.3 V, C_L = 15 pF - ensures timing-critical signal routing in high-speed digital control paths.
I_off	±10 μA max - blocks damaging back-current when V_CC = 0 V, supporting safe partial power-down in modular systems.
Output Drive	±24 mA at V_CC = 3.3 V - drives multiple LVC/LVT inputs or small capacitive loads without external buffers.
Input Voltage Tolerance	–0.5 V to 5.5 V - accepts 5-V signals while operating from 1.8-V supply, simplifying mixed-supply interface design.
Operating Temperature	–55°C to 125°C - qualified for extended-temperature industrial, aerospace, and under-hood automotive applications.
ICC (max)	10 μA - minimizes quiescent power in always-on monitoring circuits and battery-backed subsystems.

Pinout & Package

CLVC1G32MDCKREPG4 is housed in a 5-pin SC-70 (DCK) package measuring 2.15 mm × 1.40 mm × 1.1 mm (max height), with gull-wing leads, RoHS-compliant NiPdAu finish, and MSL Level-1 rating (260°C peak reflow).

Pin/Terminal	Circuit Role	Design Meaning
1	A Input	First OR gate input; accepts voltages up to 5.5 V regardless of V_CC value.
2	B Input	Second OR gate input; electrically identical to Pin 1, fully 5.5-V tolerant.
3	GND	Ground reference for logic thresholds and internal biasing; must be connected before V_CC.
4	V_CC	Positive supply rail; powers internal logic and defines output swing (0 V to V_CC).
5	Y Output	OR function result (Y = A + B); sinks or sources up to ±24 mA at 3.3 V with rail-aligned VOH/VOL.

Key Features

Feature	Design Value
I_off Partial Power-Down Support	Disables outputs when V_CC = 0 V, eliminating back-current paths in unpowered subsystems - essential for hot-plug and modular power architecture.
5.5-V Tolerant Inputs	Accepts 5-V logic signals while operating from as low as 1.65 V, removing need for discrete level translators in mixed-voltage designs.
Extended Temperature Range	–55°C to 125°C operation validated per JEDEC JESD22 and biased 85/85 HAST - suitable for aerospace, industrial control, and engine bay electronics.
Low Dynamic Power	21 pF typical power dissipation capacitance at 3.3 V enables <1 mW operation at 10 MHz - ideal for energy-constrained edge nodes.
Latch-Up Immunity	Exceeds 100 mA per JESD 78 Class II - prevents destructive latch-up during transient overvoltage or ESD events in noisy environments.

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
SN74LVC1G32IDCKREP	Same silicon, rated for –40°C to 85°C (vs. –55°C to 125°C); top-side marking CG0 vs. BYB.	Not qualified for extended-temperature industrial or aerospace use; limited to commercial/industrial ambient environments.	Select only if operating temperature stays above –40°C and cost sensitivity outweighs reliability margin.
SN74LVC1G32MDBVREP	Same functionality and temperature grade, but in 5-pin SOT-23 (DBV) package - 3.0 mm × 1.75 mm vs. DCK's 2.15 mm × 1.40 mm.	Requires larger PCB footprint and different stencil design; thermal impedance θ_JA = 324.1°C/W vs. DCK's 252°C/W.	Choose DBV only if existing layout uses SOT-23 footprints or higher thermal mass is needed for sustained 50-mA output bursts.

Compared with SN74LVC1G32IDCKREP and SN74LVC1G32MDBVREP, CLVC1G32MDCKREPG4 uniquely combines extended temperature operation (–55°C to 125°C), ultra-compact SC-70 packaging, and industry-leading thermal performance - making it optimal for size- and reliability-critical embedded systems where board space and environmental resilience are non-negotiable.

FAQ

What is the maximum input voltage CLVC1G32MDCKREPG4 can tolerate?

CLVC1G32MDCKREPG4 accepts input voltages from –0.5 V to 5.5 V, independent of V_CC level. This allows direct connection of 5-V signals even when operating from a 1.8-V supply - a key feature for voltage-level interoperability in mixed-supply systems. The absolute maximum rating is strictly enforced per datasheet Section 6.1.

Does CLVC1G32MDCKREPG4 support partial power-down mode?

Yes, CLVC1G32MDCKREPG4 integrates I_off circuitry that disables outputs when V_CC = 0 V, limiting I_off to ±10 μA maximum. This prevents damaging back-current flow from powered signal lines into unpowered sections - a critical capability for hot-swap architectures and modular power systems.

What is the propagation delay of CLVC1G32MDCKREPG4 at 3.3 V?

At V_CC = 3.3 V with C_L = 15 pF, CLVC1G32MDCKREPG4 achieves a maximum propagation delay (t_pd) of 3.6 ns. This value is measured from input transition (1.65 V threshold) to output transition (1.65 V threshold) and is guaranteed across the full operating temperature range (–55°C to 125°C).

Is CLVC1G32MDCKREPG4 pin-compatible with other LVC1G32 variants?

CLVC1G32MDCKREPG4 shares identical 5-pin SC-70 (DCK) pinout with SN74LVC1G32IDCKREP and SN74LVC1G32MDCKREP - all follow the same top-view pin assignment (Pin 1 = A, Pin 2 = B, Pin 3 = GND, Pin 4 = V_CC, Pin 5 = Y). Mechanical compatibility is confirmed per TI package drawing DCK0005A.

What is the operating temperature range for CLVC1G32MDCKREPG4?

CLVC1G32MDCKREPG4 is qualified for continuous operation from –55°C to 125°C ambient temperature. This extended range is verified per JEDEC JESD22-A108 and includes biased 85/85 testing, HAST, temperature cycling, and electromigration analysis - meeting requirements for aerospace, industrial, and under-hood automotive applications.
