Product details
Overview
74LVTH162244GRDR from Texas Instruments is a 3.3-V ABT 16-bit buffer/driver with 3-state outputs, designed for mixed-mode signal interfacing between 3.3-V logic and 5-V TTL systems. It provides true output polarity, four independent 4-bit channels, and integrated 22-Ω series output resistors to suppress overshoot/undershoot. Used in high-speed bus interface applications requiring hot-insertion support and low ground bounce.
For engineers reviewing the 74LVTH162244GRDR datasheet, 74LVTH162244GRDR pinout, 74LVTH162244GRDR application, or 74LVTH162244GRDR equivalent, key selection criteria include its 54-ball GRD microstar junior BGA package, 12-mA drive capability per output, Ioff-enabled hot-swap operation, and guaranteed 2.7-V to 3.6-V VCC operation with 5.5-V tolerant inputs.
Technical Context
The 74LVTH162244GRDR implements a flow-through pin architecture across four independent 4-bit buffer sections, each with symmetrical active-low output-enable (OE) control. Its ABT (Advanced BiCMOS Technology) core delivers TTL-compatible output levels while operating from a 3.3-V supply, enabling seamless level translation without external resistors.
Distributed VCC and GND pins minimize simultaneous switching noise, and the device supports unregulated battery operation down to 2.7 V. Power-up 3-state and Ioff circuitry ensure high-impedance outputs during power transitions and prevent backflow current when powered down.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7 V to 3.6 V - supports battery-powered and marginally regulated 3.3-V systems |
| Input Voltage Tolerance | Up to 5.5 V - enables direct connection to 5-V TTL buses without level shifters |
| Output Drive | ±12 mA per Y pin - sufficient for driving 50-pF loads at >100-MHz toggle rates |
| Propagation Delay | Typ. 3.4 ns (tPHL), 3.9 ns (tPLH) at VCC = 3.3 V - suitable for sub-200-MHz bus timing budgets |
| Output Series Resistance | 22 Ω internal - eliminates need for external termination resistors on PCB traces |
| Ioff Current | ±100 µA at VCC = 0 - prevents damaging backflow during hot insertion into live backplanes |
| Ground Bounce (VOLP) | <0.8 V at VCC = 3.3 V - reduces noise coupling into adjacent digital/analog circuits |

| 1OE, 2OE, 3OE, 4OE | Active-low output-enable controls | Four independent OE pins - enables selective 4-bit channel gating without global disable |
| VCC (Balls C3, C4, G3, G4, H7, J7) | Power supply | Six distributed VCC balls reduce IR drop and improve high-frequency decoupling |
| GND (Balls B3, B4, D3, D4, E3, E4, G7, H3, J3) | Ground reference | Nine GND balls provide low-inductance return paths for all 16 drivers |
Key Features
| Feature | Design Value |
|---|---|
| Mixed-mode voltage interface | 3.3-V VCC operation with 5-V input/output compatibility - eliminates external level translators in 3.3/5-V hybrid systems |
| Integrated 22-Ω output series resistors | Reduces PCB component count and layout complexity - no external termination required for controlled-impedance trace routing |
| Hot-insertion support | Ioff and power-up 3-state ensure safe insertion into live backplanes - prevents bus contention and supply rail disturbance |
| Flow-through pin architecture | Input-to-output signal path aligned across package edges - simplifies layer stacking and minimizes trace crossovers in dense PCB layouts |
| Distributed power/ground network | 6 VCC + 9 GND balls - lowers simultaneous switching noise (SSN) and improves signal integrity at >100-MHz data rates |
Applications
| PCI Bus Interface | Memory Module Buffering |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVT162244ADGVR | TVSOP-48 package (4.4 mm × 6.1 mm), 48-pin surface-mount; same electrical specs but different pinout and thermal profile. | Preferred for prototyping and manual assembly due to gull-wing leads; less suitable for high-density BGA-only layouts. | Select SN74LVT162244ADGVR when board space allows larger footprint and hand-soldering or rework is required. |
| SN74LVC16244ADLR | Lower drive strength (±24 mA), 1.65–3.6 V VCC range, no integrated series resistors, LVC logic family. | Better suited for 1.8-V/2.5-V systems; requires external termination for high-speed routing; lacks Ioff for hot-swap. | Choose SN74LVC16244ADLR only for cost-sensitive, non-hot-swap designs operating below 3.3 V with external impedance control. |
Compared with SN74LVT162244ADGVR, 74LVTH162244GRDR offers superior board density and thermal performance in BGA form, while SN74LVC16244ADLR trades off hot-swap safety and integrated termination for wider VCC flexibility and lower static power - neither is pin-compatible with 74LVTH162244GRDR.

FAQ
What is the package type and ball count for 74LVTH162244GRDR?
The 74LVTH162244GRDR uses a 54-ball microstar junior BGA package (GRD), with a 5.8 mm × 8.3 mm body size and 0.8-mm ball pitch. This compact, lead-free package meets JEDEC MO-194 standards and is optimized for high-density PCB layouts requiring minimal footprint and superior thermal performance compared to TSSOP or SSOP alternatives.
Does 74LVTH162244GRDR support hot insertion into live systems?
Yes, 74LVTH162244GRDR supports hot insertion via two integrated features: Ioff circuitry disables outputs when VCC = 0, preventing backflow current, and power-up 3-state forces outputs into high-impedance during power ramp-up/down. These functions are fully specified per JEDEC JESD78 Class II latch-up requirements and validated across –40°C to 85°C operation.
What is the maximum input voltage tolerance for 74LVTH162244GRDR?
The 74LVTH162244GRDR accepts input voltages up to 5.5 V regardless of VCC level, enabling direct interfacing with 5-V TTL logic families while operating from a 3.3-V supply. This 5-V tolerance is guaranteed across the full recommended operating temperature range and does not require external clamping diodes or current-limiting resistors.
How does the internal 22-Ω series resistor affect signal integrity in 74LVTH162244GRDR?
The 22-Ω series resistor integrated into each output of 74LVTH162244GRDR dampens transmission-line reflections on PCB traces, reducing overshoot and undershoot without external components. This feature maintains signal fidelity for edge rates typical of 100-MHz+ buses and eliminates layout dependencies on trace length or characteristic impedance matching.
Can 74LVTH162244GRDR operate below 3.3 V, and what is the minimum functional VCC?
Yes, 74LVTH162244GRDR is fully specified to operate from 2.7 V to 3.6 V. At 2.7 V, it maintains 12-mA output drive, 5.5-V input tolerance, and sub-6-ns propagation delay - making it suitable for battery-powered or marginally regulated systems where supply voltage may sag under load.
