Product details
Overview
SN74LVT16244BGRDR from Texas Instruments is a 3.3-V ABT 16-bit noninverting buffer/driver with 3-state outputs, designed for mixed-mode signal operation between 3.3-V and 5-V systems. It delivers ±64 mA output drive at VCC = 3.3 V, supports hot insertion via Ioff and power-up 3-state, and operates across –40°C to 85°C. It is used in high-speed bus interface applications such as memory address/data buffering in industrial control backplanes.
For engineers reviewing the SN74LVT16244BGRDR datasheet, SN74LVT16244BGRDR pinout, SN74LVT16244BGRDR application, or SN74LVT16244BGRDR equivalent, key selection criteria include 3.3-V supply compatibility, 5-V tolerant inputs/outputs, low ground bounce (<0.8 V), symmetrical active-low OE control per 4-bit group, and FBGA-54 (GRD) package thermal performance (θJA = 36°C/W).
Technical Context
The SN74LVT16244BGRDR implements four independent 4-bit noninverting buffers, each with dedicated active-low output-enable (OE) inputs (1OE–4OE). Its Advanced BiCMOS Technology (ABT) enables TTL-level interfacing while operating from a 2.7–3.6-V supply, supporting unregulated battery input down to 2.7 V.
It features Ioff circuitry that disables outputs during power-down to prevent current backflow, and power-up 3-state logic that forces outputs into high-impedance during VCC ramp-up or ramp-down when VCC is below 1.5 V. Input clamp current exceeds –50 mA, and latch-up performance exceeds 100 mA per JESD 78 Class II.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply Range | 2.7 V to 3.6 V - Enables stable operation under unregulated battery or noisy rail conditions. |
| IOL / IOH Drive | 64 mA sink / –32 mA source at VCC = 3.3 V - Sufficient for driving 50-pF loads at >100 MHz bus speeds. |
| tPLH / tPHL Propagation | 2.3 ns / 2.0 ns typical at VCC = 3.3 V, CL = 50 pF - Supports sub-5-ns timing budgets in high-speed address/data paths. |
| VIL / VIH Thresholds | 0.8 V / 2.0 V - Compatible with TTL and LVTTL logic families without level shifters. |
| VOL / VOH Output Levels | 0.5 V max at IOL = 64 mA / 2.0 V min at IOH = –32 mA - Ensures noise margin >0.4 V in 3.3-V systems. |
| IOFF Leakage | ±100 µA at VCC = 0 V - Prevents damaging back-current during hot-swap or partial-power-down scenarios. |
| θJA Thermal Resistance | 36°C/W (GRD package) - Allows sustained 16-bit drive at ambient up to 85°C with minimal heatsinking. |

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 |
|---|---|---|---|
| SN74LVC16244ADGGR | Lower drive (24 mA), 1.65–3.6-V VCC range, no 5-V tolerance - requires external clamping for 5-V interfaces. | Suitable only for pure 3.3-V or lower-voltage systems; not interoperable with 5-V peripherals. | Select when cost and power efficiency outweigh mixed-voltage interface needs. |
| 74ALVC16244DGG | Same 5-V tolerant inputs, but 24 mA drive and higher VOL (0.8 V @ 24 mA); lacks Ioff and power-up 3-state. | Not qualified for hot-swap; requires external power sequencing or OE management for safe insertion. | Choose only for fixed-power, non-hot-pluggable designs where ABT-level performance is unnecessary. |
Compared with SN74LVC16244ADGGR and 74ALVC16244DGG, SN74LVT16244BGRDR uniquely combines 5-V I/O tolerance, ±64 mA drive, Ioff-enabled hot insertion, and guaranteed 3-state behavior during power transitions - making it the sole option for robust, mixed-voltage, high-current bus interfacing in industrial and telecom infrastructure.

FAQ
What is the maximum operating temperature for SN74LVT16244BGRDR?
The SN74LVT16244BGRDR is rated for operation from –40°C to +85°C ambient temperature. This industrial-grade specification ensures reliable performance in programmable logic controllers, base station equipment, and other embedded systems exposed to elevated thermal environments without derating.
Does SN74LVT16244BGRDR support hot insertion?
Yes, SN74LVT16244BGRDR supports hot insertion through two integrated features: Ioff circuitry disables outputs when VCC = 0 V to prevent back-current, and power-up 3-state logic forces outputs into high-impedance during VCC ramp-up or ramp-down below 1.5 V - both confirmed in TI's SCBS716E datasheet.
Can SN74LVT16244BGRDR interface directly with 5-V logic?
Yes, SN74LVT16244BGRDR accepts 5-V input signals and drives 5-V loads while powered from a 3.3-V supply. Its inputs tolerate up to 5.5 V, and outputs swing rail-to-rail up to VCC + 0.5 V, enabling direct TTL-level interfacing without external level shifters.
What is the ball pitch and package footprint of SN74LVT16244BGRDR?
SN74LVT16244BGRDR uses a 54-ball GRD package with 0.5-mm ball pitch, 7.0 mm × 5.5 mm body size, and 1.0-mm maximum height. Land pattern recommendations are provided in TI's DGG0048A mechanical drawing, including solder mask-defined pads and 0.3-mm stencil apertures.
How many independent 3-state control inputs does SN74LVT16244BGRDR have?
SN74LVT16244BGRDR has four independent active-low output-enable inputs: 1OE, 2OE, 3OE, and 4OE - each controlling a separate 4-bit buffer section. This allows granular bus segmentation and concurrent enable/disable of address, data, control, or status groups within a single device.
