Nexperia USA Inc. 74LVC1G34GV,125

Overview

74LVC1G34GV,125 from Nexperia is a single non-inverting CMOS buffer with Schmitt-trigger inputs, designed for level translation between 1.65 V–5.5 V logic domains in mixed-voltage systems. It delivers ±24 mA output drive at 3.0 V, features IOFF partial power-down protection, and operates across –40 °C to +125 °C - enabling use in industrial I/O conditioning, sensor interface buffering, and FPGA/CPLD GPIO expansion.

For engineers reviewing the 74LVC1G34GV,125 datasheet, 74LVC1G34GV,125 pinout, 74LVC1G34GV,125 application, or 74LVC1G34GV,125 equivalent, this device serves as a robust, low-power, overvoltage-tolerant buffer where input noise immunity, rail-to-rail compatibility, and safe power-down behavior are critical selection criteria.

Technical Context

The 74LVC1G34GV implements a single unidirectional buffer stage with hysteresis-enabled Schmitt-trigger inputs, allowing reliable operation with slow-rising or noisy signals without external RC filtering. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.

It supports JEDEC-compliant voltage interfaces across four supply ranges (1.65–1.95 V, 2.3–2.7 V, 2.7–3.6 V, 4.5–5.5 V), maintains TTL-level compatibility, and achieves propagation delays as low as 0.5 ns at 5.0 V while sustaining full performance up to +125 °C ambient.

FAQ

Is the 74LVC1G34GV,125 pin-compatible with other 5-pin SC-74A logic buffers?

Yes - it shares the standard SC-74A (SOT753) pinout: Pin 1 (n.c.), Pin 2 (A), Pin 3 (GND), Pin 4 (Y), Pin 5 (VCC). This matches industry-standard 5-pin logic buffers like 74LVC1G00, 74LVC1G04, and 74LVC1G14, enabling footprint reuse in layout design.

Does the IOFF feature require external circuitry to function?

No - IOFF is fully internal and automatic. When VCC drops to 0 V, the output Y is actively disabled regardless of input A state, preventing back-current flow. No pull-up/down resistors or control signals are needed to activate this protection.

Can the 74LVC1G34GV,125 drive a 50 pF load at 10 MHz while maintaining signal integrity?

Yes - with CPD = 15 pF and tpd ≤ 4.1 ns (at 3.3 V), it easily handles 10 MHz square waves into 50 pF. Measured propagation delay remains stable across temperature and supply, and output drive (±24 mA) ensures fast edge rates (<2.5 ns rise/fall) under that load.

What is the significance of the 'YN' marking on the 74LVC1G34GV,125 package?

'YN' is the standardized Nexperia top-side marking code for the 74LVC1G34 family in SC-74A (SOT753) packaging. It identifies the device function and package type unambiguously - distinct from 'YN' markings on other packages (e.g., TSSOP5 or XSON6), which share the same code but differ in physical dimensions and thermal performance.
