Texas Instruments CLVC2G17MDCKREPG4

Overview

CLVC2G17MDCKREPG4 from Texas Instruments is a dual Schmitt-trigger buffer IC designed for 1.65-V to 5.5-V operation, featuring two independent noninverting buffers with hysteresis (ΔVT up to 2.0 V), ±24-mA output drive at 3.3 V, and 5.4-ns max propagation delay. It enables robust signal conditioning in noisy industrial sensor interfaces and level-translating I/O expansion circuits.

For engineers reviewing the CLVC2G17MDCKREPG4 datasheet, CLVC2G17MDCKREPG4 pinout, CLVC2G17MDCKREPG4 application, or CLVC2G17MDCKREPG4 equivalent, key selection criteria include Ioff-enabled partial-power-down support, 5.5-V-tolerant inputs, SC-70 (DCK) 6-pin package footprint, and guaranteed hysteresis across –55°C to 125°C.

Technical Context

This device implements two independent Schmitt-trigger buffers (Y = A) with distinct positive-going (VT+) and negative-going (VT–) input thresholds-e.g., VT+ = 3.1 V and VT– = 2.0 V at VCC = 4.5 V-enabling noise immunity in slow-rising or noisy digital signals. Its Ioff circuitry actively disables outputs during power-down, blocking reverse current flow when VCC = 0 V.

The CLVC2G17MDCKREPG4 supports mixed-voltage system interfacing: inputs accept up to 5.5 V regardless of VCC (1.65–5.5 V), and outputs swing rail-to-rail (VOH ≥ VCC – 0.1 V, VOL ≤ 0.55 V at 24 mA). It is qualified per JEDEC standards for extended temperature operation (–55°C to 125°C) with HAST, temperature cycling, and electromigration validation.

FAQ

What is the maximum input voltage CLVC2G17MDCKREPG4 can tolerate?

The CLVC2G17MDCKREPG4 accepts input voltages from –0.5 V to 5.5 V, independent of VCC level. This 5.5-V tolerance allows direct connection to higher-voltage sources (e.g., 5-V sensors or legacy peripherals) even when powered from 1.8 V or 2.5 V, eliminating need for external level-shifting components in mixed-voltage systems.

Does CLVC2G17MDCKREPG4 support partial power-down operation?

Yes, CLVC2G17MDCKREPG4 incorporates Ioff circuitry that disables both outputs and blocks current backflow when VCC = 0 V. This feature is essential for hot-swap applications and modular systems where subsystems may be powered independently, preventing damage to upstream drivers during power sequencing or field replacement.

What is the hysteresis voltage (ΔVT) of CLVC2G17MDCKREPG4 at 3.3 V supply?

At VCC = 3.3 V, CLVC2G17MDCKREPG4 exhibits a typical hysteresis of 1.5 V (VT+ = 2.2 V, VT– = 0.7 V), with a minimum of 0.4 V and maximum of 1.5 V across temperature and process variation. This wide hysteresis ensures reliable noise rejection for slow or noisy signals such as mechanical switch inputs or analog comparator outputs.

Can CLVC2G17MDCKREPG4 drive multiple LVC loads simultaneously?

Yes, CLVC2G17MDCKREPG4 provides ±24-mA output drive capability at 3.3 V, sufficient to drive up to 10 standard LVC inputs (each ~1 µA) or several LVT loads with capacitive loading up to 50 pF. Its rail-to-rail VOH/VOL performance ensures logic-level compatibility without degradation, even under full load.

Is CLVC2G17MDCKREPG4 suitable for automotive applications?

CLVC2G17MDCKREPG4 is an Enhanced Product (EP) variant qualified for –55°C to 125°C operation with JEDEC-recommended reliability testing (HAST, temperature cycling, electromigration), making it suitable for under-hood and chassis applications. For ASIL-B safety-critical automotive systems, TI recommends the AEC-Q100 qualified SN74LVC2G17-Q1 instead.
