Product details
Overview
SN74LV6T17PWREP from Texas Instruments is a radiation-hardened, enhanced-product hex Schmitt-trigger buffer with integrated level translation. It performs Y = A logic on six independent channels, supports 1.8V–5.5V supply operation, enables bidirectional voltage translation (e.g., 1.2V→1.8V up-translation and 5.0V→1.8V down-translation), and delivers ≤12.5 ns propagation delay at 5V with 50 pF load - used in space-grade interface bridging between mixed-voltage subsystems.
For engineers reviewing the SN74LV6T17PWREP datasheet, SN74LV6T17PWREP pinout, SN74LV6T17PWREP application, or SN74LV6T17PWREP equivalent, key selection criteria include its 5.5V-tolerant inputs, Schmitt-trigger noise immunity (ΔVT ≥ 0.35 V), 150 Mbps data rate capability, -55°C to +125°C operating range, and TSSOP-14 package compatibility with legacy LVxT logic footprints.
Technical Context
The SN74LV6T17PWREP implements six identical CMOS push-pull buffer channels, each with Schmitt-trigger input architecture providing hysteresis (ΔVT = 0.35–1.4 V depending on VCC) to reject slow-rising or noisy signals. Its LVxT input structure features reduced VIH/VIL thresholds for up-translation and 5.5V absolute input tolerance for down-translation.
Each channel operates as a non-inverting buffer (Y = A) referenced to a single VCC rail (1.6–5.5 V); output levels conform to CMOS standards at 1.8V, 2.5V, 3.3V, or 5V. Input transition rate must exceed 20 ns/V to avoid excessive dynamic current, and unused inputs require termination to VCC or GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6 V to 5.5 V - supports direct integration into mixed-voltage systems without external regulators |
| Input Voltage Tolerance | Up to 5.5 V - enables robust down-translation from 5V/3.3V/2.5V sources into lower-VCC domains |
| Propagation Delay (tPHL/tPLH) | 5.3 ns / 4.2 ns at 5V, CL = 15 pF - ensures timing-critical signal integrity in high-speed control paths |
| Hysteresis (ΔVT) | Min 0.35 V at 1.8V VCC - suppresses chatter on slow or EMI-prone signals such as reset lines or sensor outputs |
| Output Drive Strength | ±15 mA at 3.3V–5.0V VCC - sufficient to drive 50 pF loads or parallel multiple receivers without buffering |
| Operating Temperature | -55°C to +125°C - qualified for extended-life aerospace, defense, and downhole industrial applications |
| ESD Rating (HBM) | ±2000 V - meets MIL-STD-883 Class 3B handling requirements for high-reliability assembly |
Pinout & Package
PW package: 14-pin Thin Shrink Small Outline Package (TSSOP), 5.0 mm × 6.4 mm body with 0.65 mm lead pitch, JEDEC MO-153 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A, 5A, 6A | Input A for Channels 1–6 | 5.5V-tolerant Schmitt-trigger inputs enabling mixed-voltage signal reception |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex Schmitt-trigger buffer with level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LV6T07PWREP | Inverting buffer (Y = NOT A); identical voltage translation, timing, and EP qualification | Requires logic inversion in signal path - unsuitable where polarity must be preserved | Select when system-level logic demands inverted output; otherwise use SN74LV6T17PWREP for direct buffering |
| SN74LVC1G17DBVR | Single-channel, non-EP grade, commercial temperature range (-40°C to +85°C), no 5.5V input tolerance | Lacks radiation hardening, extended temperature, and robust input tolerance - limited to benign environments | Acceptable only for cost-sensitive terrestrial prototypes; not suitable for flight or mission-critical deployment |
Compared with SN74LV6T07PWREP and SN74LVC1G17DBVR, the SN74LV6T17PWREP uniquely combines non-inverting functionality, full military-grade EP qualification, and 5.5V-tolerant inputs - making it the sole option for radiation-hardened, mixed-voltage, polarity-critical aerospace and defense interfaces.

FAQ
What is the maximum input voltage the SN74LV6T17PWREP can tolerate?
The SN74LV6T17PWREP supports absolute maximum input voltage of 7 V per Absolute Maximum Ratings, but its guaranteed 5.5V-tolerant operation allows safe down-translation from 5.0V, 3.3V, and 2.5V sources without external protection. Exceeding 5.5V risks violating recommended operating conditions and may degrade long-term reliability even if within absolute limits. Always reference VI and VO ratings in Section 5.1 of the SN74LV6T17PWREP datasheet for design margining.
Does the SN74LV6T17PWREP require external pull-up or pull-down resistors on unused inputs?
Yes - unused inputs on the SN74LV6T17PWREP must be terminated to either VCC or GND to prevent floating states that cause excessive ICC, oscillation, or undefined outputs. A 10-kΩ resistor is recommended per TI application guidance. Direct connection is acceptable if the input remains permanently inactive; pull-up/pull-down is required when intermittent driving occurs. Leaving any input unconnected violates the SN74LV6T17PWREP Recommended Operating Conditions and risks functional failure.
Can the SN74LV6T17PWREP perform level translation between 1.2V and 3.3V domains?
Yes - the SN74LV6T17PWREP supports 1.2V-to-1.8V up-translation and 1.8V-to-3.3V up-translation when VCC = 3.3V, but does not directly translate 1.2V-to-3.3V in a single stage. For 1.2V source to 3.3V sink, configure two cascaded SN74LV6T17PWREP devices: first with VCC = 1.8V (1.2V→1.8V), second with VCC = 3.3V (1.8V→3.3V). This two-stage approach preserves signal integrity and meets hysteresis requirements across both transitions.
What is the typical propagation delay of the SN74LV6T17PWREP at 3.3V supply?
At VCC = 3.3V and CL = 15 pF, the SN74LV6T17PWREP exhibits typical propagation delays of tPLH = 5.4 ns and tPHL = 7.9 ns per channel, as specified in Section 5.6 of the datasheet. These values scale predictably with load capacitance - e.g., at CL = 50 pF, tPLH increases to 7.8 ns and tPHL to 10.2 ns. Delays remain tightly matched across all six channels, supporting synchronous multi-signal routing in timing-critical applications.
Is the SN74LV6T17PWREP pin-compatible with standard TSSOP-14 logic devices?
Yes - the SN74LV6T17PWREP uses the industry-standard PW (TSSOP-14) package with 0.65 mm pitch and JEDEC MO-153 mechanical dimensions, ensuring drop-in compatibility with PCB footprints designed for SN74LV6Txx, SN74LVC16xxx, and other 14-pin TSSOP logic families. Pin functions match conventional hex buffer layouts: inputs on odd pins (1,3,5,9,11,13), outputs on even pins (2,4,6,8,10,12), VCC on pin 14, and GND on pin 7 - verified in Figure 4-1 and Table 4-1 of the SN74LV6T17PWREP datasheet.
