Product details

Overview

74AUP1T34GXXL from Nexperia is a single-channel dual-supply translating buffer with independent VCC(A) and VCC(Y) rails (1.1 V to 3.6 V), Schmitt-trigger input for noise immunity, IOFF partial power-down protection, and guaranteed operation from −40 °C to +125 °C - used in voltage-level translation between mixed-voltage subsystems in portable IoT sensors and low-power MCU peripherals.

For engineers reviewing the 74AUP1T34GXXL datasheet, 74AUP1T34GXXL pinout, 74AUP1T34GXXL application, or 74AUP1T34GXXL equivalent, key selection criteria include dual-rail supply flexibility, sub-1 µA static ICC, IOFF-enabled safe power sequencing, and propagation delay under 7 ns at 3.3 V/3.3 V with 15 pF load.

Technical Context

This device implements a unidirectional A→Y buffer with input referenced to VCC(A) and output referenced to VCC(Y), enabling level translation across non-matching logic domains without direction control or enable signals. The Schmitt-trigger input ensures robust operation with slow-rising signals and high noise immunity.

IOFF circuitry actively disables the output when either supply is near 0 V, blocking backflow current during partial power-down - critical for hot-swap and battery-backed systems. It complies with JEDEC standards JESD8-7, JESD8-5, and JESD8-B across its full 1.1 V–3.6 V operating range.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Range	VCC(A): 1.1 V–3.6 V; VCC(Y): 1.1 V–3.6 V - supports independent rail translation between ultra-low-voltage sensors and higher-voltage interfaces
Static ICC	≤ 0.9 µA max - enables multi-year battery life in always-on sensor nodes
IOFF Leakage	±0.2 µA max - prevents damaging back-current during asymmetric power sequencing
Propagation Delay	1.4 ns–9.3 ns (CL = 5–30 pF, VCC = 1.1–3.6 V) - meets timing budgets for 100+ MHz digital control loops
Input Threshold	VIL ≤ 0.35×VCC(A); VIH ≥ 0.65×VCC(A) - ensures reliable switching across all supported voltages
ESD Rating	HBM > 5000 V, CDM > 1000 V - survives handling and board-level ESD events without shielding
Operating Temp	−40 °C to +125 °C - qualified for automotive under-hood and industrial motor-control environments

Pinout & Package

74AUP1T34GXXL is supplied in the SOT353-1 (TSSOP5) package: plastic thin shrink small outline, 5-lead, 1.25 mm body width, 0.65 mm pitch. Pin 1 is marked by a dot or bevel on the lower-left corner.

Pin/Terminal	Circuit Role	Design Meaning
VCC(A)	Input-side supply rail	Reference for input threshold and Schmitt hysteresis; must be stable before A transitions
A	Data input	Schmitt-triggered signal source; tolerant of slow edges and noise up to ±30 % VCC(A)
GND	Common reference	Shared ground return for both supply domains; required for IOFF functionality
Y	Data output	CMOS output referenced to VCC(Y); drives loads up to 4 mA with <0.5 V VOL at 3.0 V
VCC(Y)	Output-side supply rail	Determines VOH/VOL levels and output drive strength; independent of VCC(A)

Key Features

Feature	Design Value
Dual independent supplies	VCC(A) and VCC(Y) each configurable 1.1 V–3.6 V - eliminates need for external level shifters in mixed-voltage SoC interconnects
IOFF partial power-down	Output disabled with leakage <±0.2 µA when either VCC = 0 V - enables safe hot-plug and battery backup isolation
Schmitt-trigger input	Hysteresis ≥ 0.3×VCC(A) - rejects noise on long PCB traces and enables direct connection to mechanical switches or analog comparators
Ultra-low static power	ICC ≤ 0.9 µA at 25 °C - reduces system standby power in always-on edge devices
Wide temperature range	Specified from −40 °C to +125 °C - supports deployment in automotive engine control units and industrial PLC I/O modules

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-supply buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1T34DBVR	Single-supply only (1.65 V–5.5 V); no independent VCC(A)/VCC(Y); no IOFF	Requires matched input/output rails; unsuitable for asymmetric power-down scenarios	Select only when both sides operate at same voltage and partial power-down is not required
TXB0101DCKR	Auto-direction sensing; bidirectional; higher ICC (10 µA typ); larger X2SON6 footprint	Supports bidirectional data flow but adds complexity for simple unidirectional use cases	Prefer only when bus arbitration or dynamic direction control is needed

Compared with SN74LVC1T34DBVR and TXB0101DCKR, the 74AUP1T34GXXL uniquely delivers true dual-rail independence, sub-1 µA static consumption, and certified IOFF behavior - making it optimal for deterministic unidirectional translation in energy-constrained, mixed-voltage systems.

FAQ

What is the maximum allowable voltage difference between VCC(A) and VCC(Y)?

The datasheet does not specify a maximum differential voltage limit. Both supplies are rated independently from −0.5 V to +4.6 V absolute, and functional operation is guaranteed when each is within 1.1 V–3.6 V. However, simultaneous application of VCC(A) = 3.6 V and VCC(Y) = 1.1 V is fully supported and commonly used in level translation designs.

Can the 74AUP1T34GXXL drive a 50 pF load reliably?

No - the datasheet specifies dynamic characteristics only up to 30 pF load capacitance. At CL = 30 pF and VCC = 3.3 V, tpd reaches ~8.5 ns (max). Driving 50 pF would increase delay unpredictably and may violate setup/hold timing in high-speed interfaces; a buffer with higher drive strength or reduced trace capacitance is recommended.

Is the Schmitt-trigger hysteresis fixed or voltage-dependent?

Hysteresis is voltage-dependent and scales with VCC(A). Typical hysteresis is ≥0.3×VCC(A) - e.g., ~0.36 V at 1.2 V supply and ~1.08 V at 3.6 V supply. This ensures consistent noise margin across the entire 1.1 V–3.6 V operating range without external biasing.

Does GND need to be connected even if one supply is powered down?

Yes - GND must remain connected at all times. The IOFF circuit relies on a common reference to detect VCC(A) or VCC(Y) collapse. Floating GND compromises IOFF functionality and may allow destructive back-current paths through internal ESD structures.
