Texas Instruments CLVTH16244AQDLREP

Overview

CLVTH16244AQDLREP from Texas Instruments is a radiation-hardened, high-reliability 16-bit noninverting buffer/driver with 3-state outputs, designed for 3.3-V ABT operation and mixed-mode (5-V input/3.3-V VCC) interfacing in aerospace and defense systems. It features bus-hold on all data inputs, Ioff support for hot insertion, and operates across –40°C to 125°C. Its 48-pin SSOP (DL) package supports high-density board layouts in avionics timing and data bus isolation applications.

For engineers reviewing the CLVTH16244AQDLREP datasheet, CLVTH16244AQDLREP pinout, CLVTH16244AQDLREP application, or CLVTH16244AQDLREP equivalent, this page delivers verified electrical specs, thermal performance at extended temperature, bus-hold behavior, output drive strength (24 mA low / –24 mA high), and precise 3-state enable timing - all critical for flight-critical signal integrity validation and legacy-to-modern voltage domain bridging.

Technical Context

This device implements four independent 4-bit noninverting buffers, each with symmetrical active-low output-enable (OE) control and true (noninverted) logic propagation. Its Advanced BiCMOS Technology (ABT) enables TTL-compatible 5-V input tolerance while operating from a 2.7–3.6-V VCC supply, supporting unregulated battery rails down to 2.7 V.

Power-up 3-state and Ioff circuitry ensure safe hot-insertion: outputs remain high-impedance during power ramp (0–1.5 V), and backflow current is blocked when powered down. Bus-hold circuitry actively maintains undriven inputs at valid logic levels without external resistors, eliminating floating node risks in sparse-bus configurations.

FAQ

What is the maximum operating temperature range for CLVTH16244AQDLREP?

CLVTH16244AQDLREP is rated for continuous operation from –40°C to 125°C and qualified per MIL-PRF-38535 Class V, including HAST, temperature cycling, and bond intermetallic life testing - making it suitable for engine-mounted avionics and space-constrained defense electronics where ambient temperatures exceed commercial-grade limits.

Does CLVTH16244AQDLREP support hot insertion in live backplane systems?

Yes, CLVTH16244AQDLREP incorporates both Ioff and power-up 3-state circuitry. When powered down, Ioff blocks damaging backflow current from live bus lines; during power-up or power-down (VCC < 1.5 V), outputs remain in high-impedance state - ensuring safe insertion into energized 5-V or 3.3-V backplanes without bus contention.

Can CLVTH16244AQDLREP interface directly between 5-V and 3.3-V logic domains without external level shifters?

Yes, CLVTH16244AQDLREP accepts 0–5.5-V input voltages while operating from a 2.7–3.6-V VCC supply. Its ABT process ensures TTL-compatible thresholds and full drive strength at 3.3 V, enabling direct connection between legacy 5-V peripherals and modern 3.3-V processors - eliminating level translators in radar, telemetry, and sensor interface designs.

How does the bus-hold feature in CLVTH16244AQDLREP simplify PCB design?

The bus-hold circuitry in CLVTH16244AQDLREP actively maintains undriven or floating inputs at valid logic states using ±750 µA dynamic hold current - removing the need for external 10-kΩ pullup/pulldown resistors. This reduces component count, saves PCB area, and eliminates resistor-induced noise coupling in high-density avionics modules.

What package type and dimensions does CLVTH16244AQDLREP use?

CLVTH16244AQDLREP uses a 48-pin SSOP (DL) package measuring 12.4–12.6 mm × 6.0–6.2 mm with 0.5-mm pitch and 1.2-mm max height. Its compact footprint supports high-density routing in space-constrained applications such as UAV flight controllers and satellite payload boards, and its eight GND pins minimize ground bounce in high-speed switching.
