Nexperia USA Inc. 74LVC3G17DP,125

Overview

74LVC3G17DP from Nexperia is a triple non-inverting Schmitt trigger buffer with 5 V tolerant inputs, designed for signal conditioning in mixed-voltage digital systems. It operates from 1.65 V to 5.5 V supply, delivers ±24 mA output drive at 3.0 V, features IOFF partial power-down protection, and supports operation from –40 °C to +125 °C - enabling robust noise immunity in industrial sensor interfaces and level translation between 3.3 V microcontrollers and 5 V peripherals.

For engineers reviewing the 74LVC3G17DP datasheet, 74LVC3G17DP pinout, 74LVC3G17DP application, or 74LVC3G17DP equivalent, this device is selected for its Schmitt-trigger hysteresis (min 0.4 V at 3.0 V), 5.5 V overvoltage-tolerant inputs, TSSOP8 package compatibility, and guaranteed performance across automotive-grade temperature range without requiring external pull-ups or clamping diodes.

Technical Context

The 74LVC3G17DP implements three independent non-inverting Schmitt-trigger buffers in a single TSSOP8 package. Each channel provides hysteresis (VH) of 0.40–1.40 V depending on VCC, with positive-going threshold VT+ ranging from 1.30 V (at 3.0 V) to 2.91 V (at 5.5 V) and negative-going threshold VT– from 0.60 V to 1.86 V - ensuring reliable waveform shaping in noisy environments.

Its IOFF circuitry actively disables outputs when VCC = 0 V, blocking backflow current up to ±50 mA, while input leakage remains ≤±1 μA and supply current stays below 4 μA under static conditions - making it suitable for hot-swap and battery-backed subsystems where power sequencing is uncontrolled.

FAQ

Can 74LVC3G17DP operate with VCC = 1.8 V while accepting 5 V inputs?

Yes. The device is explicitly rated for 5.5 V input tolerance across its full 1.65–5.5 V supply range. At VCC = 1.8 V, inputs up to 5 V are safely clamped internally without damage or logic corruption - verified per JESD8-7 compliance and absolute maximum ratings (VI = –0.5 to +6.5 V).

Does 74LVC3G17DP require external pull-up resistors on inputs or outputs?

No. Inputs are CMOS-compatible with ≤±1 μA leakage and defined thresholds (VT+, VT–) across VCC; outputs have active push-pull drivers capable of sourcing/sinking ±24 mA. Pull-ups are unnecessary unless interfacing with open-drain sources or implementing wired-OR logic - not required for standard Schmitt-trigger operation.

What is the maximum capacitive load the 74LVC3G17DP can drive reliably?

Based on dynamic characteristics and CPD = 16.3 pF per buffer, the device maintains <5.4 ns propagation delay driving up to 50 pF (per Table 11 test condition). For sustained 100 MHz operation, total load (including trace + probe + IC input) should remain ≤30 pF to avoid excessive rise/fall time degradation beyond 2.5 ns.

How does IOFF functionality behave when VCC is ramping during power-up?

IOFF activates only when VCC reaches 0 V - not during ramp-up. During power-on, the device behaves as a normal Schmitt trigger. Once powered down to 0 V, IOFF forces outputs into high-impedance state within nanoseconds, blocking back-current even if inputs remain at 5 V - confirmed by IOFF leakage ≤±2 μA at VI = 5.5 V and VCC = 0 V.
