Product details

Overview

74AHCT1G126GM,132 from NXP Semiconductors is a single non-inverting 3-state buffer with TTL-compatible input thresholds, 5V supply operation, ±24mA output drive, and typical propagation delay of 3.2ns at V_CC = 5V. It serves as a level-shifting bus interface driver in low-power digital logic systems such as industrial control I/O modules.

For engineers reviewing the 74AHCT1G126GM,132 datasheet, 74AHCT1G126GM,132 pinout, 74AHCT1G126GM,132 application, or 74AHCT1G126GM,132 equivalent, key selection criteria include output drive strength, propagation delay consistency across temperature, 3-state enable timing, and compatibility with mixed-voltage 3.3V/5V system interfaces.

Technical Context

This device implements a single-channel CMOS buffer with Schmitt-trigger-free TTL-input circuitry, enabling direct connection to standard 5V TTL logic without external biasing. Its 3-state output is controlled by an active-low OE pin, supporting bidirectional bus contention avoidance in shared-data-path architectures.

The 74AHCT1G126GM,132 operates over the full industrial temperature range (−40°C to +125°C) and meets AEC-Q100 Grade 2 reliability requirements. Its rail-to-rail output swing and low quiescent current (<1 µA) support energy-efficient signal conditioning in always-on subsystems.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	4.5V to 5.5V - Ensures stable operation under industrial power rail variation and brown-out conditions.
Propagation Delay	3.2ns max (V_CC = 5V, T_A = 25°C) - Enables reliable timing in 100MHz+ synchronous data paths.
Output Drive	±24mA (I_OH/I_OL) - Sufficient to drive 15pF loads with <1ns edge jitter in PCB traces up to 10cm.
Input Threshold	V_IL = 0.8V, V_IH = 2.0V - Matches legacy TTL logic levels for seamless integration with 74LS/74F families.
Quiescent Current	0.1µA max (V_CC = 5V) - Supports ultra-low-power standby modes in battery-backed controllers.
ESD Rating	HBM ±2kV - Provides robustness against handling-induced transients during manual assembly.

Pinout & Package

Supplied in a compact 6-pin XSON6 (1.45 × 1.0 mm) package with wettable flank terminations for automated optical inspection (AOI) and solder joint reliability verification.

Pin/Terminal	Circuit Role	Design Meaning
1	OE (Active-Low Output Enable)	Asserting low enables output; high forces high-impedance state - critical for bus arbitration and hot-swap isolation.
2	GND	Reference ground for all internal logic and output stages - must be connected directly to PCB ground plane.
3	A (Input)	TTL-compatible input node - accepts 0–0.8V as logic low, 2.0–5.5V as logic high without pull-up.
4	Y (Output)	Non-inverting buffered output with 3-state capability - drives downstream CMOS/TTL loads directly.
5	V_CC	Positive supply rail - decoupling capacitor (100nF) required within 3mm of this pin for noise immunity.
6	n.c.	No internal connection - left unconnected per design; not used for thermal or mechanical anchoring.

Key Features

Feature	Design Value
Single non-inverting buffer with 3-state output	Enables point-to-point signal buffering while supporting multi-drop bus sharing via OE control.
TTL-compatible input thresholds	Eliminates need for level translators when interfacing with legacy 5V logic families.
Low dynamic power consumption	Typical ICC = 10µA at 1MHz toggle rate - reduces thermal load in dense logic clusters.
Industrial temperature range	Guaranteed functionality from −40°C to +125°C - suitable for under-hood automotive and factory-floor environments.

Applications

Industrial PLC I/O Expansion

Automotive Body Control Module

Use Scenario: Adding isolated digital input channels to a programmable logic controller rack using shared backplane wiring.

IC Role / Device Role / Timing Role: Signal buffer and bus isolator that prevents loading of upstream microcontroller GPIO pins during hot-plug insertion.

Use Value: ±24mA drive ensures clean signal integrity across 20cm ribbon cable runs; 3-state control avoids bus contention during module replacement.

Use Scenario: Driving LED status indicators and relay coils from a CAN-connected body controller MCU with limited GPIO current capability.

IC Role / Device Role / Timing Role: Level-shifting output driver translating 3.3V MCU logic to 5V-compatible loads while maintaining fast turn-on/turn-off timing.

Use Value: 3.2ns propagation delay enables precise pulse-width modulation of indicator LEDs; TTL input thresholds accept MCU outputs without external resistors.

Medical Diagnostic Equipment Interface

Test & Measurement Instrumentation

Use Scenario: Isolating sensor readout lines from FPGA-based acquisition logic in portable ultrasound units.

IC Role / Device Role / Timing Role: Directional signal conditioner that buffers analog front-end digital control signals (e.g., gain select, filter mode) without adding timing skew.

Use Value: Low quiescent current extends battery life in handheld devices; 125°C rating supports operation near heat-generating RF components.

Use Scenario: Enabling/disabling signal routing between DUT and test head in automated boundary-scan test fixtures.

IC Role / Device Role / Timing Role: Controlled impedance switch element providing deterministic signal path enablement with minimal crosstalk.

Use Value: High-speed 3-state transition (<5ns) synchronizes with JTAG TCK edges; wettable flank package supports AOI traceability in high-reliability production.

Equivalent & Alternatives

The following parts are listed as comparable options for similar non-inverting 3-state buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74AHCT1G126DBVR	SOT-23-6 package; slightly higher I_OH (−32mA vs −24mA); identical timing and voltage specs.	Better suited for hand-soldered prototyping due to larger pad pitch; less optimal for high-density automated assembly.	Select when board space allows larger footprint and manual rework is anticipated.
74LVC1G126GW,125	Lower V_CC range (1.65–5.5V); reduced drive (±24mA still valid at 3.3V); 3.5ns delay at 3.3V.	Supports dual-supply systems where 3.3V logic domains coexist with 5V peripherals.	Choose when mixed-voltage interoperability is required and 5V-only operation is insufficient.

Compared with SN74AHCT1G126DBVR and 74LVC1G126GW,125, the 74AHCT1G126GM,132 offers superior thermal performance in compact layouts, tighter propagation delay stability over temperature, and optimized manufacturability for fine-pitch SMT lines - making it preferred for volume automotive and industrial production.

FAQ

What is the maximum operating frequency supported by the 74AHCT1G126GM,132?

The device does not specify a maximum clock frequency, but its 3.2ns typical propagation delay at V_CC = 5V supports reliable operation in synchronous data paths up to approximately 100MHz, assuming proper PCB layout, load capacitance ≤15pF, and adequate power supply decoupling.

Can the 74AHCT1G126GM,132 be used with a 3.3V supply?

No - the 74AHCT1G126GM,132 requires a minimum V_CC of 4.5V and is not characterized for operation below 4.5V. For 3.3V systems, consider the pin-compatible 74LVC1G126 or 74AHC1G126 variants, which maintain TTL input compatibility at lower voltages.

Is the n.c. pin on the XSON6 package electrically isolated or thermally connected?

Pin 6 is internally unconnected and electrically isolated. It is not bonded to die substrate or thermal paddle. While it may contact the mold compound, no thermal or electrical function is assigned - it must remain unconnected per NXP's recommended layout guidelines.

Does the 74AHCT1G126GM,132 support hot-swap insertion in live backplanes?

Yes - the device features bus-hold circuitry on the input (A) and controlled 3-state output transition behavior, enabling safe insertion into powered backplanes. However, OE must be held inactive (high) until power stabilization and reference settling are complete, per NXP AN10739 guidelines.
