Product details
Overview
SN74LVC2G34MDCKREP from Texas Instruments is a dual non-inverting buffer gate operating from 1.65 V to 5.5 V, delivering ±24 mA output drive at 3.3 V, 4.1 ns max propagation delay at 3.3 V, and Ioff support for partial-power-down mode. It serves as a level-shifting signal repeater in space-constrained logic interfaces.
For engineers reviewing the SN74LVC2G34MDCKREP datasheet, SN74LVC2G34MDCKREP pinout, SN74LVC2G34MDCKREP application, or SN74LVC2G34MDCKREP equivalent, key selection criteria include guaranteed 1.65–5.5 V operation, ±24-mA drive strength at 3.3 V, Ioff-enabled backflow protection, low 10-µA ICC, and SC-70 (DCK) 6-pin package compatibility with high-density PCB layouts.
Technical Context
The SN74LVC2G34MDCKREP implements two independent positive-logic buffers (Y = A), each with rail-to-rail input tolerance up to 5.5 V and output voltage clamping within –0.5 V to VCC + 0.5 V. Its Ioff circuitry actively disables outputs during power-down, preventing current backflow when VCC = 0 V.
Designed for extended temperature operation (–55°C to 125°C), it meets JEDEC JESD 78 Class II latch-up immunity (>100 mA), exceeds JESD 22 ESD ratings (2000-V HBM, 200-V MM, 1000-V CDM), and features low ground bounce (VOLP < 0.8 V) and undershoot (VOHV > 2 V) at 3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |

FAQ
What is the maximum operating temperature range for SN74LVC2G34MDCKREP?
The SN74LVC2G34MDCKREP is fully specified from –55°C to 125°C ambient temperature. This extended range is validated per JEDEC and industry standards including biased 85/85 testing, temperature cycling, and HAST, making it suitable for under-hood automotive, avionics, and downhole industrial applications where thermal resilience is mandatory. The SN74LVC2G34MDCKREP maintains full electrical performance across this entire range.
Does SN74LVC2G34MDCKREP support partial-power-down operation?
Yes, the SN74LVC2G34MDCKREP includes integrated Ioff circuitry that disables both outputs when VCC = 0 V, limiting Ioff current to ±10 µA. This prevents damaging current backflow from live inputs into a powered-down device-a critical feature for hot-swap systems, multi-rail power sequencing, and battery-backed subsystems. The SN74LVC2G34MDCKREP is explicitly designed and tested for this behavior per datasheet Section 6.5.
What package type and dimensions does SN74LVC2G34MDCKREP use?
The SN74LVC2G34MDCKREP uses the SC-70 (DCK) package: a 6-pin, ultra-compact surface-mount outline measuring 1.8 mm × 1.4 mm × 1.1 mm (max height). Its NanoFree™ construction eliminates the leadframe, using the silicon die itself as the package body-reducing parasitic inductance and improving thermal performance. The SN74LVC2G34MDCKREP pinout matches JEDEC MO-203 AB standard.
Can SN74LVC2G34MDCKREP interface between 1.8-V and 5-V logic domains?
Yes, the SN74LVC2G34MDCKREP supports true 1.65–5.5 V VCC operation and accepts input voltages from –0.5 V to 5.5 V-regardless of VCC level. This allows it to safely buffer signals from a 5-V source into a 1.8-V system (with VCC = 1.8 V), or vice versa, without external level-shifting components. The SN74LVC2G34MDCKREP achieves this via robust input clamp structures and rail-to-rail input stage design.
Is SN74LVC2G34MDCKREP qualified for aerospace or defense applications?
Yes, the SN74LVC2G34MDCKREP is an enhanced-product (EP) device with qualification pedigree per V62/06659-01XE, meeting MIL-PRF-38535 requirements for reliability, traceability, and extended temperature operation. It undergoes rigorous testing-including HAST, temperature cycling, and latch-up immunity exceeding 100 mA per JESD 78 Class II-making it suitable for spaceflight, defense electronics, and other high-assurance environments. The SN74LVC2G34MDCKREP carries full QML-V traceability documentation.
