Nexperia USA Inc. 74LV1T126GVH

Overview

74LV1T126GV from Nexperia is a single-supply, 5-pin CMOS level-translating buffer/line driver with 3-state output, supporting bidirectional voltage translation (1.8 V ↔ 3.3 V, 2.5 V ↔ 3.3 V, 3.3 V ↔ 5.0 V) and 5 V tolerant inputs. It operates across -40 °C to +125 °C, delivers propagation delay as low as 3.2 ns at 5.0 V/15 pF, and features ±25 mA output drive capability for interfacing between mixed-voltage logic domains in portable and industrial control systems.

For engineers reviewing the 74LV1T126GV datasheet, 74LV1T126GV pinout, 74LV1T126GV application, or 74LV1T126GV equivalent, key selection criteria include its single-supply operation across 1.6–5.5 V, guaranteed 3-state disable timing (tdis ≤ 6.8 ns), 5 V input tolerance enabling legacy interface compatibility, and thermal-enhanced SC-74A (SOT753) package with 0.95 mm lead pitch and 1.3 mm body width.

Technical Context

This device implements a non-inverting, enable-controlled buffer architecture where the OE input directly gates the output Y into high-impedance state. Its input threshold adapts dynamically to VCC-enabling up-translation (e.g., 1.8 V input → 3.3 V output at VCC = 3.3 V) and down-translation (e.g., 3.3 V input → 2.5 V output at VCC = 2.5 V)-without external biasing or dual supplies.

Logic behavior follows standard TTL/CMOS-compatible function table: OE = HIGH enables pass-through (Y = A); OE = LOW forces Y to high-Z. Input leakage remains ≤ ±1 μA over full temperature range, and output drive strength is specified at ±2.3 mA to ±8 mA depending on VCC and load condition, ensuring robust signal integrity across voltage domains.

Key Specifications

Pinout & Package

FAQ

What is the maximum recommended operating voltage for 74LV1T126GV?

The absolute maximum supply voltage is +7.0 V, but the recommended operating range is 1.6 V to 5.5 V per the datasheet. Operation above 5.5 V risks exceeding internal oxide breakdown limits and invalidates parametric guarantees - sustained use beyond 5.5 V may cause irreversible damage even if initial functionality appears normal.

Can 74LV1T126GV translate 5 V inputs down to 1.8 V outputs?

Yes - with VCC = 1.8 V, the device supports down-translation from 3.3 V or 5 V inputs to 1.8 V CMOS output levels. The 5 V tolerant inputs ensure safe operation, and VOH/VOL specifications (e.g., VOH ≥ 1.45 V at IO = –2 mA) meet 1.8 V logic thresholds across –40 °C to +125 °C.

Is the SC-74A (SOT753) package RoHS compliant and lead-free?

Yes - the 74LV1T126GV in SOT753 packaging is fully RoHS compliant and lead-free, with homogeneous material composition verified per EU Directive 2011/65/EU and JEDEC J-STD-609A Class 3 marking. Terminal finish is matte tin (Sn), and reflow profile adheres to IPC/JEDEC J-STD-020D.3.

Does 74LV1T126GV require external pull-up or pull-down resistors on OE or A pins?

No - OE and A have CMOS-compatible input structure with ≤ ±1 μA leakage; no external biasing is needed. However, OE should be actively driven (not left floating) to prevent unintended output enable/disable states. In systems with noisy environments, a 10 kΩ pull-down on OE is recommended for default OFF-state safety.
