Texas Instruments CLVTH16244AIDGVREP

Overview

CLVTH16244AIDGVREP from Texas Instruments is a 3.3-V ABT 16-bit buffer/driver with 3-state outputs, designed for low-voltage bus interfacing in mixed-signal systems. It provides true outputs, four independent 4-bit buffers, and supports 5-V input tolerance with 3.3-V VCC - enabling TTL-level compatibility in 3.3-V domains. Used in industrial backplane drivers and FPGA I/O expansion.

For engineers reviewing the CLVTH16244AIDGVREP datasheet, CLVTH16244AIDGVREP pinout, CLVTH16244AIDGVREP application, or CLVTH16244AIDGVREP equivalent, key selection criteria include 3-state enable timing (tPZH/tPLZ ≤ 5.4 ns), bus-hold inputs eliminating external resistors, hot-insertion support via Ioff and power-up 3-state, and operation across –40°C to 85°C.

Technical Context

This device implements Advanced BiCMOS Technology (ABT) for low static power and high-speed performance at 3.3 V. Each of its four 4-bit sections features symmetrical active-low output-enable (OE) inputs and true (non-inverting) logic outputs.

It integrates bus-hold circuitry on all data inputs to maintain valid logic states when undriven, and includes Ioff protection that disables outputs during power-down to prevent current backflow - critical for live insertion into powered backplanes.

FAQ

What is the maximum operating temperature range for CLVTH16244AIDGVREP?

CLVTH16244AIDGVREP is specified for continuous operation from –40°C to +85°C. This extended industrial temperature range is validated per JEDEC standards including HAST, temperature cycling, and autoclave testing - ensuring reliability in harsh environments such as factory automation and outdoor communications equipment. The device maintains full electrical specifications across this entire range.

Does CLVTH16244AIDGVREP support hot insertion into a live backplane?

Yes, CLVTH16244AIDGVREP supports hot insertion via two integrated features: Ioff circuitry disables outputs when VCC = 0 V to prevent back-current flow, and power-up 3-state ensures outputs remain high-impedance during power ramp-up. These capabilities are fully characterized and qualified per TI's Enhanced Product requirements - making CLVTH16244AIDGVREP suitable for modular systems requiring field-replaceable line cards without system shutdown.

Can CLVTH16244AIDGVREP interface directly with 5-V TTL logic?

Yes, CLVTH16244AIDGVREP accepts 5-V TTL input levels (VIH = 2.0 V min, VIL = 0.8 V max) while operating from a 3.3-V VCC supply. Its ABT input structure tolerates up to 5.5 V on input pins, enabling direct connection to legacy 5-V systems without external level shifters - a key advantage over standard LVC or LV families which lack 5-V tolerance.

How does the bus-hold feature on CLVTH16244AIDGVREP reduce design complexity?

The bus-hold circuitry on CLVTH16244AIDGVREP actively maintains valid logic states on all 16 data inputs when left floating, eliminating the need for 32 external pullup or pulldown resistors. This reduces BOM cost, saves PCB area, avoids routing congestion, and improves signal integrity by removing parasitic RC delays introduced by discrete terminations - especially valuable in high-density industrial control modules.

What package type and dimensions does CLVTH16244AIDGVREP use?

CLVTH16244AIDGVREP uses the TVSOP (DGV) package: a 48-pin, 0.4-mm pitch, thin very small outline package measuring 6.0 mm × 12.5 mm with 1.2 mm maximum height. Its compact footprint and fine pitch support high-density routing in space-constrained applications like portable test equipment and multi-function communication modules.
