Product details
Overview
SN74LV6T07PWREP from Texas Instruments is a radiation-hardened hex open-drain buffer IC enabling bidirectional voltage translation across 1.65V–5.5V supply domains, with 5.5V-tolerant inputs, 6.67Mbps data rate (RPU = 1kΩ, CL = 30pF), and support for up-translation (e.g., 1.2V→1.8V) and down-translation (e.g., 5V→0.8V). It serves in level-shifting interfaces between mixed-voltage communication modules and system controllers in aerospace and defense systems.
For engineers reviewing the SN74LV6T07PWREP datasheet, SN74LV6T07PWREP pinout, SN74LV6T07PWREP application, or SN74LV6T07PWREP equivalent, key selection considerations include its LVxT-enhanced input threshold architecture, open-drain output drive capability (±25mA), thermal performance (RθJA = 147.7°C/W), latch-up immunity (>250mA), and operation across –55°C to +125°C.
Technical Context
The SN74LV6T07PWREP implements six independent positive-logic buffers (Y = A) with LVxT-enhanced CMOS inputs-featuring reduced VIH/VIL thresholds for up-translation and 5.5V tolerance for down-translation. Each channel operates with supply-referenced inputs and open-drain outputs requiring external pull-ups.
Its functional mode table confirms high-impedance (Z) output state when input is HIGH and LOW output when input is LOW. Input transition rate must be ≤20 ns/V to prevent oscillation or excessive ICC, and unused inputs must be terminated to VCC or GND-not left floating-to ensure deterministic logic behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - Enables interoperability across 1.2V, 1.8V, 2.5V, 3.3V, and 5V logic domains without level-shifter ICs. |
| Input Voltage Tolerance | Up to 5.5V - Allows direct connection of higher-voltage signals (e.g., 5V microcontroller GPIO) to lower-VCC domains (e.g., 1.8V FPGA I/O). |
| Output Drive Current | ±25mA per channel - Supports driving LEDs, wired-AND buses, or moderate capacitive loads (≤50pF) with controlled VOL. |
| Propagation Delay | 5.3ns (tPHL, 5V, CL=15pF) - Ensures timing compliance in high-speed control paths such as sensor interface enable lines. |
| Operating Temperature | –55°C to +125°C - Qualified for extended-temperature military and space-grade applications with full parameter validation. |
| Latch-up Immunity | >250mA per JESD17 - Guarantees robustness against transient current surges in harsh ESD or power-rail fault conditions. |
| Input Leakage Current | ±0.1µA (TA = 25°C) - Minimizes static power draw and avoids false triggering in low-power wake-up circuits. |
Pinout & Package
PW package: 14-pin TSSOP (5 mm × 6.4 mm body with 5 mm × 4.4 mm footprint), lead-free and RoHS-compliant, qualified for enhanced product (EP) reliability under MIL-PRF-38535.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A–6A | Input A (6 channels) | LVxT-enhanced CMOS inputs accepting 0–5.5V signals; VIH/VIL thresholds scale with VCC for translation flexibility. |
| 1Y–6Y | Open-drain Output Y (6 channels) | High-impedance when HIGH, actively pulls LOW; requires external pull-up for logic HIGH; supports wired-AND bus topologies. |
| VCC | Positive Supply | Single supply pin setting logic thresholds and output swing; determines translation direction and VOL/IO limits. |
| GND | Ground Reference | Return path for all output sink current and supply return; must handle total IOUT + ICC (max ±50mA combined). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Level Translation | Eliminates discrete resistor-divider or dedicated translator ICs by supporting both up-translation (1.2V→1.8V) and down-translation (5V→0.8V) within one device. |
| Enhanced Input Thresholds | VIH(MIN) = 1.1V @ 1.65–2V VCC enables reliable recognition of sub-1.8V logic highs from ultra-low-power sensors or MCUs. |
| 5.5V-Tolerant Inputs | Accepts legacy 5V TTL/CMOS signals directly into 1.8V or 2.5V systems without clamping diodes or external protection. |
| Open-Drain Flexibility | Enables shared-bus signaling (e.g., I²C-like arbitration), LED drive with external anode pull-up, and mixed-voltage wired-AND logic. |
| Radiation-Hardened EP Qualification | Meets enhanced product requirements for TID ≥ 100 krad(Si), SEL immunity, and extended temperature operation in space and defense platforms. |
Applications
| Industrial Sensor Interface | Aerospace Data Bus Isolation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage translation buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC6T245QPWRQ1 | 3.3V-only supply; dual-directional (bus transceiver); no open-drain outputs; higher ICC (20µA typical vs. 2µA). | Requires separate direction control; unsuitable for wired-AND or LED drive; limited to 3.3V domain bridging. | Choose only if bidirectional data transfer (not unidirectional enable/control) is required and VCC is fixed at 3.3V. |
| TXB0106PWR | Auto-sensing direction; 1.2V–3.6V VCCA/VCCB dual supplies; no 5.5V input tolerance; lower temp range (–40°C to +85°C). | Not qualified for extended temperature or radiation environments; lacks latch-up immunity spec; unsuitable for 5V input sources. | Select only for commercial automotive infotainment where auto-direction and dual-rail flexibility outweigh radiation/temperature requirements. |
Compared with SN74LVC6T245QPWRQ1 and TXB0106PWR, the SN74LV6T07PWREP uniquely combines radiation-hardened EP qualification, 5.5V-tolerant inputs, open-drain outputs for wired-AND/LED use, and full –55°C to +125°C operation-making it the sole option for mission-critical aerospace enable/control signaling where reliability trumps bidirectionality or auto-sensing convenience.

FAQ
What is the maximum input voltage the SN74LV6T07PWREP can tolerate?
The SN74LV6T07PWREP supports input voltages up to 5.5V regardless of VCC setting-verified per Absolute Maximum Ratings. This allows direct interfacing of 5V signals (e.g., legacy microcontrollers) into lower-voltage domains (e.g., 1.8V FPGAs) without external clamping. The 5.5V tolerance applies to all six input pins (1A–6A) and is maintained across the full operating temperature range (–55°C to +125°C).
Can the SN74LV6T07PWREP perform up-translation from 1.2V to 3.3V?
Yes-the SN74LV6T07PWREP supports up-translation from 1.2V to 3.3V when operated with a 3.3V VCC supply. Per the LVxT feature description, its reduced VIH threshold (1.45V min @ 3V–3.6V VCC) ensures reliable recognition of 1.2V logic HIGH inputs, while the open-drain output pulled to 3.3V delivers full-swing 3.3V-compatible signals. This is validated in TI's application examples and electrical characteristics tables.
Does the SN74LV6T07PWREP require external pull-up resistors on its outputs?
Yes-every SN74LV6T07PWREP output (1Y–6Y) is open-drain and cannot source current. An external pull-up resistor is mandatory to establish a defined HIGH logic level. Recommended values range from 1kΩ (for speed-critical 6.67Mbps operation) to 10kΩ (for low-power LED drive); the exact value depends on load capacitance, rise time requirements, and supply voltage (VPU ≠ VCC).
What is the latch-up immunity rating for the SN74LV6T07PWREP?
The SN74LV6T07PWREP exceeds 250mA latch-up immunity per JESD17, verified during enhanced product (EP) qualification. This specification ensures robust operation in high-noise environments such as radar subsystems or power converter controls, where transient ground bounce or supply coupling could otherwise trigger destructive latch-up events.
Is the SN74LV6T07PWREP compatible with I²C bus protocols?
No-the SN74LV6T07PWREP is not I²C-compatible. While its open-drain outputs support wired-AND topology, it lacks built-in slew-rate control, noise filtering, or bus arbitration logic required for I²C compliance. It may be used for simple I²C-like signaling (e.g., interrupt lines) but does not meet I²C electrical specifications (e.g., VOL ≤ 0.4V at 3mA, rise time limits) and must be evaluated per system-level timing analysis.
