Texas Instruments 1P1G14MDBVREPG4

Overview

1P1G14MDBVREPG4 from Texas Instruments is a single Schmitt-trigger inverter IC designed for 1.65-V to 5.5-V VCC operation, delivering hysteresis-based noise immunity with VT+ = 1.50 V and VT– = 0.84 V at 3 V, 4.6 ns max propagation delay at 3.3 V, ±24-mA output drive, and Ioff support for partial-power-down mode - used in signal conditioning of noisy digital inputs in industrial sensor interfaces.

For engineers reviewing the 1P1G14MDBVREPG4 datasheet, 1P1G14MDBVREPG4 pinout, 1P1G14MDBVREPG4 application, or 1P1G14MDBVREPG4 equivalent, key selection criteria include Schmitt threshold symmetry, Ioff-enabled power sequencing compatibility, SOT-23 (DBV) package thermal resistance (324°C/W), and extended temperature range (–55°C to 125°C) for harsh-environment deployment.

Technical Context

This device implements a single inverter with positive- and negative-going input thresholds (VT+, VT–) enabling robust noise rejection on slow or noisy signals. Its logic function Y = A is realized via CMOS LVC technology with rail-to-rail input tolerance up to 5.5 V independent of VCC.

The Ioff circuitry actively disables outputs during power-down, blocking reverse current flow between powered and unpowered rails. Propagation delay varies with supply voltage (e.g., 4.6 ns max at 3.3 V, 5.0 ns max at 5 V) and load capacitance (15 pF), supporting timing-critical edge detection in mixed-voltage systems.

FAQ

What is the exact function and logic behavior of the 1P1G14MDBVREPG4?

The 1P1G14MDBVREPG4 is a single Schmitt-trigger inverter implementing the Boolean function Y = A. It features asymmetric input thresholds (VT+ and VT–) to provide hysteresis, ensuring clean output transitions even with slow or noisy input edges. Its output is a true CMOS push-pull stage, and the device operates across 1.65 V to 5.5 V VCC. All functional behavior matches the SN74LVC1G14-EP specification sheet.

Does the 1P1G14MDBVREPG4 support partial-power-down operation, and how is it implemented?

Yes, the 1P1G14MDBVREPG4 supports partial-power-down operation via its Ioff circuitry. When VCC = 0 V, the Ioff feature disables both output FETs, limiting input/output leakage to ±10 µA and preventing damaging current backflow from live inputs or outputs into the unpowered device. This behavior is fully characterized and guaranteed across –55°C to 125°C.

What are the absolute maximum ratings for the 1P1G14MDBVREPG4, and why do they matter in rugged designs?

The 1P1G14MDBVREPG4 has absolute maximum ratings of –0.5 V to 6.5 V on VCC, VI, and VO pins, ±50 mA continuous output current, and –55°C to 150°C storage temperature. These limits define safe operating boundaries beyond which permanent damage may occur. In rugged designs, respecting the 6.5 V absolute max on inputs - even when VCC is 1.65 V - avoids latch-up and ensures robustness against transient overvoltage events.

How does the hysteresis of the 1P1G14MDBVREPG4 improve noise immunity compared to a standard inverter?

The 1P1G14MDBVREPG4 provides 0.66 V hysteresis (ΔVT = VT+ – VT–) at 3 V supply, meaning the input must rise above 1.50 V to trigger a low-to-high output transition and fall below 0.84 V to trigger high-to-low. This window rejects noise spikes ≤ 660 mV and prevents oscillation on slow edges - unlike standard inverters, which switch at a single threshold and are prone to chatter under similar conditions.

Is the 1P1G14MDBVREPG4 pin-compatible with other members of the SN74LVC1G14 family, and what package variants exist?

Yes, the 1P1G14MDBVREPG4 is pin-compatible with SN74LVC1G14MDBVREP and V62/07626-01XE - all use the SOT-23 (DBV) 5-pin package with identical pinout (Pin 1 = NC, Pin 2 = A, Pin 3 = GND, Pin 4 = Y, Pin 5 = VCC). The alternate DCK (SOP-5) variant has different pin assignment and footprint, so it is not mechanically or electrically interchangeable without PCB redesign.
