Product details
Overview
CLVTH16244AQDGGREP 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.
For engineers reviewing the CLVTH16244AQDGGREP datasheet, CLVTH16244AQDGGREP pinout, CLVTH16244AQDGGREP application, or CLVTH16244AQDGGREP equivalent, key selection considerations include its TSSOP-48 package, guaranteed 3.3-V operation down to 2.7 V, ±24 mA output drive at VCC = 3.3 V, and compliance with extended temperature and enhanced product-change notification requirements for mission-critical embedded control.
Technical Context
This device implements four independent 4-bit noninverting buffers, each with symmetrical active-low output-enable (OE) control. Its Advanced BiCMOS Technology (ABT) architecture delivers low static power dissipation while supporting TTL-level inputs at 5 V with a 3.3-V supply.
The CLVTH16244AQDGGREP integrates bus-hold circuitry on all 16 data inputs-eliminating external pullup/pulldown resistors-and includes Ioff and power-up 3-state logic to prevent backflow current and driver conflict during hot insertion or power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7 V to 3.6 V - supports unregulated battery operation and ensures stable logic levels across wide supply variation. |
| IOL / IOH | ±24 mA at VCC = 3.3 V - sufficient drive strength for fanout to multiple CMOS/TTL loads without external buffering. |
| Propagation Delay | tPLH/tPHL ≤ 4.6 ns at VCC = 3.3 V - enables high-speed data routing in real-time avionics and test equipment buses. |
| Bus-Hold Current | ±750 µA at VCC = 3.6 V - actively maintains valid logic state on floating inputs, preventing metastability in unterminated backplanes. |
| Operating Temperature | –40°C to 125°C - qualified per JEDEC HAST, temperature cycle, and autoclave testing for extended-life deployment in harsh environments. |
| ESD Rating | 2000-V HBM, 200-V MM - exceeds JESD22-A114/A115, reducing risk of field failure during handling or system integration. |
| Output Enable Setup | tsu(OE) ≥ 1.2 ns - ensures reliable 3-state transition timing when synchronizing with clocked control signals in FPGA-adjacent interfaces. |
Pinout & Package
TSSOP-48 (DGG) package: 12.5 mm × 6.1 mm × 1.2 mm body, 0.5-mm pitch, gull-wing leads, RoHS-compliant NiPdAu finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE, 3OE, 4OE | Active-low output enable | Independent control per 4-bit group; asserts high-impedance state when high, enabling flexible bus partitioning. |
| 1A1–1A4, 2A1–2A4, 3A1–3A4, 4A1–4A4 | Data inputs | All feature integrated bus-hold; no external biasing required even when disconnected or unterminated. |
| 1Y1–1Y4, 2Y1–2Y4, 3Y1–3Y4, 4Y1–4Y4 | True buffered outputs | Noninverting, 3-state capable; sink/source ±24 mA with VOL ≤ 0.5 V and VOH ≥ 2.4 V at rated load. |
| VCC (Pins 7, 20, 31, 44) | Power supply | Four dedicated VCC pins reduce IR drop and improve noise immunity across the 16-bit data path. |
| GND (Pins 4, 10, 15, 27, 32, 39, 47) | Ground reference | Seven GND pins provide low-inductance return paths, critical for minimizing ground bounce (VOLP < 0.8 V). |
Key Features
| Feature | Design Value |
|---|---|
| Mixed-mode voltage interface | Accepts 5-V TTL inputs while operating from 3.3-V VCC - enables seamless bridging between legacy 5-V logic and modern low-voltage FPGAs or processors. |
| Hot-insertion support | Ioff and power-up 3-state ensure zero-current backflow and automatic high-Z during power ramp - eliminates need for sequencing controllers in modular backplane systems. |
| Bus-hold circuitry | Eliminates external pull resistors on all 16 inputs - reduces BOM count, PCB area, and signal integrity risks from stubs or mismatched termination. |
| Extended temperature qualification | Tested per JEDEC HAST, biased 85/85, temperature cycling, and electromigration - validated for 10+ year operation in satellite payload and engine control units. |

FAQ
What is the maximum output current specification for CLVTH16244AQDGGREP at 3.3 V?
The CLVTH16244AQDGGREP delivers ±24 mA output current per pin at VCC = 3.3 V, as specified in the Electrical Characteristics table under IOL and IOH conditions. This drive strength supports direct interfacing with multiple TTL or CMOS loads without external buffering, and remains valid across the full –40°C to 125°C operating range.
Does CLVTH16244AQDGGREP support hot-plug insertion in live backplane systems?
Yes, CLVTH16244AQDGGREP supports hot insertion via dual protection mechanisms: Ioff circuitry disables outputs when VCC = 0 V to prevent damaging backflow current, and power-up 3-state forces outputs into high-impedance during power ramp. These features are fully characterized and qualified per TI's enhanced DMS program for defense applications.
How does the bus-hold function operate on CLVTH16244AQDGGREP inputs?
The CLVTH16244AQDGGREP integrates active bus-hold circuitry on all 16 data inputs (A1–A16), which maintains the last-valid logic state when inputs float. It sources or sinks up to ±750 µA at VCC = 3.6 V, eliminating the need for external pullup/pulldown resistors and improving noise immunity in high-impedance or unterminated bus segments.
What is the pin-compatible alternative to CLVTH16244AQDGGREP for industrial-temperature applications?
SN74LVTH16244AIDGVREP is pin-compatible with CLVTH16244AQDGGREP and shares identical logic functionality, timing, and DC specifications. Its key difference is the TVSOP-48 package and –40°C to 85°C temperature rating, making it suitable for commercial-space or ground-based test equipment where extended temperature is not required.
Is CLVTH16244AQDGGREP compliant with JEDEC JESD22 reliability standards?
Yes, CLVTH16244AQDGGREP is qualified per JEDEC JESD22 standards including 2000-V HBM (A114-A) and 200-V MM (A115-A) ESD testing, plus latch-up immunity exceeding 500 mA per JESD17.
