Product details
Overview
SN74LVT162244AGRDR from Texas Instruments is a 3.3-V ABT 16-bit buffer/driver IC with 3-state outputs, designed for mixed-mode signal interfacing between 3.3-V logic and 5-V systems. It provides true outputs, four independent 4-bit channels, 12-mA output drive capability, integrated 22-Ω series resistors per output, and supports hot insertion via Ioff and power-up 3-state. It is used in high-speed bus interface applications requiring level translation and noise control.
For engineers reviewing the SN74LVT162244AGRDR datasheet, SN74LVT162244AGRDR pinout, SN74LVT162244AGRDR application, or SN74LVT162244AGRDR equivalent, key selection considerations include its 54-ball VFBGA (ZRD) package, 2.7–3.6-V supply range, 3.3-V ABT logic family compatibility, 12-mA sink/source drive, and support for unregulated battery operation down to 2.7 V.
Technical Context
This device implements four independent 4-bit noninverting buffers, each with an active-low 3-state output-enable (OE) input. Its ABT (Advanced BiCMOS Technology) architecture enables TTL-compatible inputs at 5 V while operating from a 3.3-V VCC, supporting mixed-voltage system interconnects without external level shifters.
The IC features distributed VCC/GND pins and flow-through pinout to minimize switching noise and optimize PCB layout. It includes built-in 22-Ω series output resistors to suppress overshoot/undershoot, and Ioff circuitry ensures no backflow current during hot insertion when powered down.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply Range | 2.7 V to 3.6 V - supports unregulated battery rails and tolerates supply droop without functional loss |
| Output Drive | ±12 mA - sufficient to drive standard TTL loads and moderate-capacitance buses directly |
| Input Voltage Range | –0.5 V to 5.5 V - accepts 5-V TTL inputs while powered from 3.3 V, enabling seamless level translation |
| Propagation Delay | Typ. 3.4 ns (tPHL), 3.9 ns (tPLH) at VCC = 3.3 V - suitable for high-speed 100-MHz bus applications |
| Output Enable Time | tPZL max 6.1 ns, tPHZ max 6.5 ns - fast transition into/out of 3-state minimizes bus contention windows |
| Power-Up 3-State | Active below 1.5 V VCC - prevents output conflict during power ramp-up or brownout conditions |
| Ioff Current | ±100 µA at VCC = 0 - blocks damaging back-current during hot-swap or partial-power-down scenarios |

Key Features
| Feature | Design Value |
|---|---|
| Mixed-mode voltage interface | 5-V tolerant inputs with 3.3-V VCC operation - eliminates external level translators in 3.3/5-V hybrid systems |
| Integrated 22-Ω output series resistors | Reduces overshoot/undershoot by >40% vs. bare CMOS drivers - improves signal integrity on FR4 traces up to 15 cm |
| Hot-insertion support | Ioff and power-up 3-state prevent backdrive and bus contention during live board replacement - required for modular telecom and server backplanes |
| Flow-through pinout architecture | Input and output pins aligned on opposite sides - enables straight-layer PCB routing and reduces vias/cross-talk in dense layouts |
| Distributed VCC/GND ball placement | 8 VCC + 12 GND balls interleaved across package - lowers effective power loop inductance and suppresses ∆I/∆t noise |

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, no integrated series resistors, LVC family | Requires external 22-Ω resistors for EMI control; not rated for 5-V input tolerance | Choose for cost-sensitive, single-supply 3.3-V-only systems where external termination is acceptable |
| SN74ALVC16244DGGR | Higher speed (tPD typ 2.5 ns), ±24 mA drive, 1.65–3.6-V VCC, ALVC family | Lacks 5-V input tolerance and Ioff - unsuitable for hot-swap or mixed-voltage environments | Prefer for high-speed 3.3-V-only buses where minimal propagation delay is critical and level translation is handled elsewhere |

FAQ
What is the package type and dimensions of SN74LVT162244AGRDR?
The SN74LVT162244AGRDR uses a 54-ball VFBGA (ZRD) package with 0.65-mm ball pitch, body size 7.1 mm × 6.9 mm, and maximum height of 1.0 mm. It complies with JEDEC MO-194 and is optimized for space-constrained, high-density PCB layouts in industrial and automotive applications.
Does SN74LVT162244AGRDR support 5-V input signals while operating from a 3.3-V supply?
Yes, the SN74LVT162244AGRDR supports input voltages up to 5.5 V with VCC = 2.7–3.6 V, enabling direct interfacing with 5-V TTL logic without external level shifters. This mixed-mode capability is explicitly specified in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official datasheet.
What is the purpose of the integrated 22-Ω series resistors on SN74LVT162244AGRDR outputs?
The integrated 22-Ω series resistors on each output of the SN74LVT162244AGRDR dampen signal edge rates to reduce overshoot and undershoot, improving signal integrity on PCB traces without requiring discrete components. This feature is confirmed in the Features section and Electrical Characteristics table of the TI datasheet SCBS718D.
Can SN74LVT162244AGRDR be used in hot-swap applications?
Yes, the SN74LVT162244AGRDR supports hot insertion via two mechanisms: Ioff circuitry disables outputs when VCC = 0 to prevent back-current, and power-up 3-state holds outputs high-impedance until VCC exceeds 1.5 V. Both features are validated per JESD78 Class II latch-up and JESD22 ESD standards.
What are the thermal characteristics of SN74LVT162244AGRDR in its ZRD package?
The SN74LVT162244AGRDR in the ZRD package has a junction-to-ambient thermal resistance (θJA) of 36°C/W, measured per JESD51-7. This value reflects the enhanced thermal performance enabled by its 54-ball VFBGA construction with distributed thermal vias and copper thermal pad exposure in recommended PCB land patterns.
