Texas Instruments CLVC16T245MDGGEP

Overview

CLVC16T245MDGGEP from Texas Instruments is a 16-bit dual-supply bus transceiver with configurable voltage translation and 3-state outputs, designed for bidirectional level-shifting between 1.65-V to 5.5-V domains (e.g., 1.8V ↔ 3.3V or 2.5V ↔ 5V). It features independent VCCA/VCCB rails, VCC isolation, Ioff partial-power-down support, and operates across –55°C to 125°C for aerospace/defense systems.

For engineers reviewing the CLVC16T245MDGGEP datasheet, CLVC16T245MDGGEP pinout, CLVC16T245MDGGEP application, or CLVC16T245MDGGEP equivalent, this page delivers verified electrical specs, thermal metrics, switching timing under military-grade temperature extremes, and real-world voltage-translation use cases - all validated against TI's SCES843A revision FEBRUARY 2013 production data.

Technical Context

The CLVC16T245MDGGEP implements two independent 8-bit transceiver sections (1A↔1B and 2A↔2B), each controlled by dedicated DIR and OE pins referenced to VCCA. Its dual-rail architecture enables asynchronous, bidirectional data flow with direction determined by DIR state and output enable governed by OE logic level.

VCC isolation ensures both ports enter high-impedance when either VCCA or VCCB is at GND; Ioff circuitry prevents backflow current during power-down. Input thresholds scale with VCCA (VIH = VCCA × 0.7, VIL = VCCA × 0.3), while overvoltage-tolerant I/Os accept up to 6.5 V regardless of supply rail.

FAQ

What voltage levels can CLVC16T245MDGGEP translate between?

The CLVC16T245MDGGEP supports bidirectional translation between any two logic domains from 1.65 V to 5.5 V per rail - including 1.8 V ↔ 2.5 V, 1.8 V ↔ 3.3 V, 2.5 V ↔ 5 V, and 3.3 V ↔ 5 V. Its VIH/VIL thresholds scale with VCCA, and I/Os tolerate up to 6.5 V regardless of supply, making CLVC16T245MDGGEP ideal for interfacing legacy and next-generation mixed-voltage systems.

Does CLVC16T245MDGGEP support partial power-down operation?

Yes, CLVC16T245MDGGEP includes Ioff circuitry that disables outputs and limits off-state current to ±10 μA when VCCA or VCCB is at 0 V. This prevents damaging current backflow during power sequencing or standby modes - a critical requirement for hot-swap-capable systems and battery-powered medical devices using CLVC16T245MDGGEP.

How does the VCC isolation feature work in CLVC16T245MDGGEP?

In CLVC16T245MDGGEP, if either VCCA or VCCB is driven to GND, both A-port and B-port outputs automatically enter high-impedance state - regardless of DIR or OE states. This hardware-level isolation prevents bus contention and latch-up during rail failure or improper power-up sequences, a key safety feature confirmed in TI's SCES843A datasheet for CLVC16T245MDGGEP.

What is the maximum data rate supported by CLVC16T245MDGGEP?

CLVC16T245MDGGEP does not specify a fixed data rate but delivers guaranteed timing performance: tPLH/tPHL ≤ 27.8 ns over –55°C to 125°C at 2.5 V supplies. At room temperature and 3.3 V, propagation delay drops to ≤ 6.1 ns, supporting >30 MHz parallel bus operation. System-level data rate depends on layout, load capacitance, and clocking scheme - CLVC16T245MDGGEP enables robust high-speed interconnects within these bounds.

Is CLVC16T245MDGGEP pin-compatible with standard SN74LVC16T245 variants?

Yes, CLVC16T245MDGGEP uses the same TSSOP-48 (DGG) package and identical pinout as commercial SN74LVC16T245 variants - including pin-for-pin mapping for all 48 terminals (VCCA, VCCB, DIR, OE, A/B I/Os, GND). The enhanced-product version adds extended temperature, tighter process controls, and traceability - but requires no PCB redesign when upgrading from standard versions.
