Texas Instruments CLVC1G125IDCKREP

Overview

CLVC1G125IDCKREP from Texas Instruments is a single-channel 3-state bus buffer gate designed for voltage-level translation and bidirectional bus isolation in low-power digital systems. It operates from 1.65 V to 5.5 V, delivers ±24 mA output drive at 3.3 V, features 3.7 ns max propagation delay (tpd) at 3.3 V, and supports Ioff partial-power-down protection. It is used in industrial control backplanes and FPGA I/O expansion interfaces where signal integrity and power sequencing matter.

For engineers reviewing the CLVC1G125IDCKREP datasheet, CLVC1G125IDCKREP pinout, CLVC1G125IDCKREP application, or CLVC1G125IDCKREP equivalent, key selection criteria include its SC-70 (DCK) 5-pin package, 3-state enable logic (active-low OE), ±24-mA drive capability at 3.3 V, and guaranteed operation from –40°C to 85°C with JESD78 latch-up compliance.

Technical Context

This device implements a noninverting buffer with active-low 3-state output control (OE). Its Ioff circuitry disables outputs and blocks current backflow when VCC = 0 V, enabling safe hot-insertion in multi-rail systems. Input tolerance up to 5.5 V allows interfacing with 5-V logic while powered from 1.8-V or 3.3-V rails.

The logic diagram confirms direct A→Y path with OE gating the output stage. Propagation delay (tpd) and enable/disable timing (ten/tdis) are characterized across VCC = 1.65–5.5 V and temperature, with worst-case tpd = 3.7 ns at 3.3 V/25°C and CL = 15 pF - critical for high-speed data routing in compact PCB layouts.

FAQ

What is the maximum operating voltage for CLVC1G125IDCKREP?

The CLVC1G125IDCKREP supports a supply voltage (VCC) range of 1.65 V to 5.5 V. Absolute maximum ratings allow up to 6.5 V on VCC, but functional operation is only guaranteed within the recommended 1.65–5.5 V range. Exceeding 5.5 V risks parametric degradation or permanent damage, per the absolute maximum ratings table in the datasheet.

Does CLVC1G125IDCKREP support hot-swap or partial-power-down operation?

Yes, CLVC1G125IDCKREP includes Ioff circuitry that limits off-state current to ±10 µA when VCC = 0 V and inputs/outputs are biased to 5.5 V. This prevents damaging current backflow during partial-power-down sequences, enabling safe hot-insertion in modular systems - a core feature confirmed in the Functional Description and Electrical Characteristics sections.

What is the pin configuration and package type of CLVC1G125IDCKREP?

CLVC1G125IDCKREP uses the SC-70 (DCK) 5-pin package with top-side marking "CMO". Pin 1 is the OE terminal, followed clockwise by A (pin 2), GND (pin 3), VCC (pin 4), and Y (pin 5). The package measures 1.85 mm × 1.40 mm × 1.10 mm max height and carries MSL Level-1 reflow rating per JEDEC J-STD-020.

Can CLVC1G125IDCKREP interface between 5-V and 3.3-V logic domains?

Yes, CLVC1G125IDCKREP accepts input voltages up to 5.5 V on both A and OE pins while operating from VCC = 3.3 V, enabling direct 5-V-to-3.3-V level translation without external components. Its output swing is rail-to-rail (0 V to VCC), so it drives 3.3-V logic correctly when VCC = 3.3 V - verified in the Recommended Operating Conditions and Electrical Characteristics tables.

What is the propagation delay performance of CLVC1G125IDCKREP at 3.3 V?

At VCC = 3.3 V, CLVC1G125IDCKREP achieves a maximum propagation delay (tpd) of 3.7 ns under CL = 15 pF and TA = 25°C, with typical value of 0.6 ns. Over the full –40°C to 85°C range, tpd remains ≤4.5 ns (CL = 50 pF), supporting reliable timing in high-speed digital interconnects - data sourced directly from the Switching Characteristics table.
