Texas Instruments SN74LV6T06PWREP

Overview

SN74LV6T06PWREP from Texas Instruments is a radiation-hardened, enhanced-product hex inverter buffer with open-drain outputs, designed for level translation across 1.8V–5.5V supply rails. It supports bidirectional voltage translation (e.g., 1.2V→1.8V up-translation and 5.0V→3.3V down-translation), delivers ≤12.5 ns propagation delay at 5V, features 5.5V-tolerant inputs, and operates from –55°C to +125°C for aerospace and defense systems.

For engineers reviewing the SN74LV6T06PWREP datasheet, SN74LV6T06PWREP pinout, SN74LV6T06PWREP application, or SN74LV6T06PWREP equivalent, key selection criteria include open-drain drive capability (±25 mA), VIH/VIL thresholds optimized for LVxT translation, latch-up immunity (>250 mA), thermal resistance (RθJA = 147.7°C/W), and TSSOP-14 package compatibility with high-reliability PCB layouts.

Technical Context

The SN74LV6T06PWREP implements six independent positive-logic inverters (Y = A) with CMOS-compatible inputs and open-drain NMOS outputs. Its LVxT input structure enables reduced VIH thresholds (e.g., 1.1 V at 1.65–2 V VCC) and 5.5 V input tolerance - enabling both up-translation (1.2 V → 1.8 V) and down-translation (5.0 V → 3.3 V) without external components.

Each channel operates with rail-referenced output logic: LOW state driven actively to GND (VOL ≤ 0.35 V @ IOL = 8 mA, 5 V), HIGH state in high-impedance (Z), requiring external pull-up. Propagation delays range from 4.2 ns (tPLH, 5 V, CL = 15 pF) to 46.7 ns (tPLH, 1.8 V, CL = 50 pF), supporting data rates up to 150 Mbps under defined load conditions.

FAQ

What is the maximum input voltage the SN74LV6T06PWREP can safely accept?

The SN74LV6T06PWREP accepts input voltages up to 5.5 V regardless of VCC level - a key feature of its LVxT architecture. This 5.5 V tolerance is explicitly specified in the Absolute Maximum Ratings table and enables direct interfacing with legacy 5 V logic without external clamping. Exceeding 5.5 V risks permanent damage, even if current is limited.

Can the SN74LV6T06PWREP perform level translation from 1.2 V to 3.3 V directly?

No - the SN74LV6T06PWREP does not support direct 1.2 V to 3.3 V up-translation. Its documented up-translation combinations are limited to 1.2 V → 1.8 V, 1.5 V → 2.5 V, 1.8 V → 3.3 V, and 3.3 V → 5.0 V. For 1.2 V → 3.3 V, two-stage translation (e.g., 1.2 V → 1.8 V → 3.3 V using cascaded SN74LV6T06PWREP units) or a dedicated multi-level translator is required.

How many channels does the SN74LV6T06PWREP provide, and what is their logical function?

The SN74LV6T06PWREP provides six independent inverter channels. Each performs the Boolean function Y = A in positive logic - meaning a HIGH input produces a LOW output (active-low inversion), and a LOW input results in high-impedance output. All six channels share the same VCC and GND, but operate electrically isolated with no internal coupling.

Is a pull-up resistor required on the outputs of the SN74LV6T06PWREP?

Yes - every open-drain output (1Y–6Y) requires an external pull-up resistor to establish a valid HIGH logic level. The value depends on speed and power needs: 10 kΩ is typical for general-purpose use, while lower values (e.g., 1–4.7 kΩ) improve rise time at the cost of higher static current. No pull-up is needed if the output drives only another open-drain input in wired-AND configuration.

What is the thermal resistance (RθJA) of the SN74LV6T06PWREP in its PW (TSSOP-14) package?

The junction-to-ambient thermal resistance (RθJA) for the SN74LV6T06PWREP in the PW package is 147.7°C/W, measured under standard JEDEC JESD51-2 conditions (single-layer board, 1 in² copper). This value assumes no additional heatsinking; actual board layout, copper area, and airflow significantly affect real-world thermal performance.
