Product details

Overview

74LVC1G34GF,132 from NXP Semiconductors is a single non-inverting buffer with 3-state output, designed for voltage-level translation between 1.65 V and 5.5 V logic domains. It features 2.9 ns typical propagation delay at 3.3 V, ±24 mA output drive capability, and operates across -40 °C to +125 °C. Used in I²C bus buffering and GPIO expansion interfaces.

For engineers reviewing the 74LVC1G34GF,132 datasheet, 74LVC1G34GF,132 pinout, 74LVC1G34GF,132 application, or 74LVC1G34GF,132 equivalent, key selection criteria include input/output voltage compatibility, 3-state control timing, output drive strength under load, and industrial temperature support.

Technical Context

This device implements a CMOS-based Schmitt-trigger input stage for noise immunity and a push-pull output stage with active 3-state control via the OE pin. The output remains high-impedance when OE is low, enabling bus sharing without contention.

It supports mixed-voltage system interfacing: inputs tolerate 5.5 V regardless of V_CC, while outputs swing rail-to-rail within the V_CC range. No internal pull-up or pull-down resistors are integrated.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 5.5 V - enables interoperability across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families
t_PD (max)	5.6 ns at V_CC = 3.3 V - ensures minimal signal delay in high-speed digital control paths
I_OH/I_OL	±24 mA at V_CC = 3.3 V - drives multiple LVC loads or small capacitive traces without external buffers
Input Voltage Tolerance	Up to 5.5 V independent of V_CC - allows safe connection to higher-voltage buses like legacy 5 V I²C segments
Operating Temperature	-40 °C to +125 °C - supports under-hood automotive and industrial control module deployment
ESD Rating	HBM ±4 kV - provides robustness against handling and board-level electrostatic discharge events

Pinout & Package

Supplied in a 6-pin XSON6 (1.45 × 1.0 mm) leadless package with wettable flanks, optimized for automated optical inspection and thermal performance in space-constrained PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
1 (A)	Input	CMOS-compatible digital input with Schmitt-trigger hysteresis for noise rejection
2 (GND)	Ground	Reference return path for all internal circuitry and output drivers
3 (Y)	Output	Push-pull, 3-state-capable output with rail-to-rail swing and ±24 mA drive
4 (OE)	Output Enable	Active-low control: Y = high-impedance when OE = low; Y = A when OE = high
5 (V_CC)	Supply	Primary power rail; sets output voltage swing and defines input logic thresholds
6 (NC)	No Connect	Internally unconnected; must be left floating or tied to GND per layout guidelines

Key Features

Feature	Design Value
Wide supply voltage range	1.65–5.5 V operation enables reuse across multiple board revisions and voltage domains
5.5 V tolerant inputs	Eliminates need for external level-shifting components when interfacing with 5 V peripherals
Low dynamic power consumption	Typical I_CC = 1 µA at 3.3 V - reduces quiescent current in always-on sensor interface nodes
Small XSON6 footprint	1.45 × 1.0 mm body with wettable flanks supports high-density routing and AOI-compatible reflow

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G34DBVR	SOT-23-5 package; no NC pin; slightly higher t_PD (6.5 ns max at 3.3 V)	Lacks wettable flanks; less suitable for AOI-reliant high-volume manufacturing	Preferred where board space permits SOT-23 and AOI is not required
74AUP1G34GW,125	Lower I_OH/I_OL (±4 mA); wider V_CC range (0.8–3.6 V); higher ESD (±6 kV HBM)	Not 5.5 V input-tolerant; unsuitable for 5 V bus interfacing	Optimal for ultra-low-power 1.8 V systems where 5 V tolerance is unnecessary

Compared with SN74LVC1G34DBVR, the 74LVC1G34GF,132 offers superior manufacturability in fine-pitch assembly and tighter timing; versus 74AUP1G34GW,125, it trades lower static power for essential 5 V input compatibility in mixed-voltage designs.

FAQ

What is the maximum capacitive load this buffer can drive while maintaining specified t_PD?

The 74LVC1G34GF,132 is characterized up to 50 pF load capacitance. At 3.3 V V_CC, t_PD remains ≤5.6 ns with C_L = 50 pF and R_PU/R_PD = 500 Ω. Driving >50 pF increases propagation delay nonlinearly and may require output series termination.

Can the NC pin be connected to GND or V_CC without affecting operation?

Pin 6 is internally unconnected and must not be tied to any voltage rail. NXP recommends leaving it floating or connecting it to GND only if required by PCB mechanical constraints - doing so has no electrical effect but avoids potential solder bridging during reflow.

Does this device support hot insertion or live bus connection?

No. While inputs are 5.5 V tolerant, the device lacks powered-off protection (I_OFF) and bus-hold circuitry. Connecting to an active bus while V_CC is unpowered may cause latch-up or excessive current draw through parasitic paths.

Is the 3-state output compatible with open-drain bus topologies?

Not directly. The output is push-pull, not open-drain. To interface with I²C or SMBus, an external pull-up resistor must be used, and the OE pin must be held high during data transfer - the buffer acts as a repeater, not a bus controller.
