Product details

Overview

MC74VHC1GT08P5T5G from onsemi is a single 2-input AND gate in SOT-953 package, featuring TTL-level input thresholds (VIH = 1.4 V min at 3.0 V VCC), 3.5 ns typical propagation delay at 5 V, ±8 mA output drive, and over-voltage tolerant inputs/outputs up to 5.5 V. It enables level-shifting between 3 V and 5 V logic domains in compact portable power management circuits.

For engineers reviewing the MC74VHC1GT08P5T5G datasheet, pinout, applications, or equivalent options, key selection criteria include input threshold compatibility with legacy TTL sources, I_OFF support for partial power-down, and guaranteed operation across −55 °C to +125 °C industrial temperature range.

Technical Context

This device implements standard positive-logic AND functionality with dual inputs (A, B) and one output (Y), operating from 2.0 V to 5.5 V supply. Its TTL-compatible input structure accepts VIH ≥ 1.4 V (at 3.0 V VCC) and VIL ≤ 0.45 V, distinguishing it from the CMOS-threshold MC74VHC1G08 variant.

Input and output structures are over-voltage tolerant to 5.5 V independent of VCC, enabling safe interfacing between 3 V microcontrollers and 5 V peripherals. The I_OFF feature ensures <10 µA leakage when VCC = 0 V, supporting hot-swap and battery-backup scenarios without damaging downstream circuitry.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	2.0 V to 5.5 V - supports mixed-voltage system integration without level translators
t_PD (typ)	3.5 ns at 5 V, CL = 15 pF - enables high-speed timing in compact control logic paths
VIH / VIL	1.4 V / 0.45 V min/max at 3.0 V - ensures reliable recognition of TTL-output signals
I_OH/I_OL	±8 mA at 3.0 V - drives multiple 74-series inputs or small LEDs directly
Over-Voltage Tolerance	Inputs/outputs withstand 5.5 V regardless of VCC - eliminates need for external clamping diodes
I_OFF	<10 µA at VCC = 0 V - prevents back-powering and signal corruption during partial power-down
Operating Temp	−55 °C to +125 °C - qualified for under-hood automotive and industrial ambient environments

Pinout & Package

SOT-953 (Case 527AE) is a 5-pin, 1.0 mm × 0.8 mm × 0.37 mm ultra-small surface-mount package with 0.35 mm pitch. Pin 1 is marked by a dot or beveled edge per onsemi mechanical drawing.

Pin/Terminal	Circuit Role	Design Meaning
1	A	First AND input - accepts TTL- or CMOS-level signals up to 5.5 V
2	GND	Ground reference - must be low-impedance for stable noise margin and I_OFF operation
3	B	Second AND input - electrically identical to Pin 1; no internal priority or sequencing
4	Y	Output - actively driven high/low; tri-state not supported; tolerates 5.5 V when VCC = 0 V
5	VCC	Positive supply - powers internal logic; voltage determines VIH/VIL thresholds and output drive strength

Key Features

Feature	Design Value
TTL-level input thresholds	Enables direct interface with legacy 74LS/74F outputs without pull-up resistors or translators
Over-voltage tolerant I/O	Allows connection to 5 V buses while powered from 3 V, eliminating external protection components
I_OFF partial power-down	Prevents current backflow and bus contention when VCC is removed but I/O lines remain active
−55 °C to +125 °C operation	Validated for use in engine control units, industrial PLCs, and outdoor sensor nodes without derating
Pb-free, RoHS-compliant	Meets global environmental regulations and reflow soldering requirements for lead-free assembly

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G08DBVR	CMOS input thresholds (VIH = 2.0 V min at 3.3 V); slightly higher t_PD (4.5 ns typ)	Requires 3.3 V–compatible input sources; less suitable for direct TTL interfacing	Select when interfacing exclusively with modern 3.3 V logic families and lower static current is prioritized
74AUP1G08GW,125	Lower VCC range (0.8–3.6 V); 3.8 ns t_PD; no 5.5 V over-voltage tolerance	Not usable in mixed 3 V/5 V systems; limited to sub-3.6 V domains	Choose for ultra-low-power battery-powered designs where 5 V tolerance is unnecessary

Compared with SN74LVC1G08DBVR and 74AUP1G08GW,125, the MC74VHC1GT08P5T5G uniquely supports TTL-level inputs and 5.5 V over-voltage tolerance at 2.0–5.5 V operation - making it the only option among the three for robust 3 V/5 V boundary interfacing without external components.

FAQ

What is the input voltage threshold behavior of MC74VHC1GT08P5T5G?

The MC74VHC1GT08P5T5G features TTL-level input thresholds: VIH is 1.4 V minimum and VIL is 0.45 V maximum at VCC = 3.0 V. This allows reliable recognition of standard TTL output levels without external biasing. Unlike its CMOS-threshold sibling MC74VHC1G08, the MC74VHC1GT08P5T5G does not require pull-up resistors when driven by 74LS or 74F series logic.

Can MC74VHC1GT08P5T5G safely interface a 5 V signal to a 3 V microcontroller?

Yes. The MC74VHC1GT08P5T5G has over-voltage tolerant inputs rated to 5.5 V regardless of VCC level. When powered from 3.0 V, it accepts 5 V input signals on pins A and B without damage or clamping, and produces a 3 V-compatible output on Y - enabling direct level translation without external components.

Does MC74VHC1GT08P5T5G support partial power-down operation?

Yes. The MC74VHC1GT08P5T5G includes I_OFF circuitry that limits power-off leakage to <10 µA when VCC = 0 V, even if input or output pins are biased to 5.5 V. This prevents back-powering of the supply rail and avoids bus contention in systems with hot-swap or battery-backup capability.

What is the propagation delay of MC74VHC1GT08P5T5G at 3.3 V supply?

At VCC = 3.3 V and CL = 15 pF, the MC74VHC1GT08P5T5G exhibits a typical propagation delay (t_PLH/t_PHL) of 4.1 ns, with a maximum of 10.5 ns over −40 °C to +85 °C. This performance is documented in the AC Electrical Characteristics table for the MC74VHC1GT08 family and applies identically to the MC74VHC1GT08P5T5G in SOT-953 package.

Is MC74VHC1GT08P5T5G qualified for automotive applications?

The base MC74VHC1GT08P5T5G is not AEC-Q100 qualified; however, onsemi offers automotive-grade variants with "−Q" suffix (e.g., MC74VHC1GT08P5T5G−Q) that are AEC-Q100 qualified and PPAP capable. These versions undergo additional stress testing and lot traceability for automotive body electronics and chassis applications.
