Product details
Overview
74ABT162244DGG,512 from Nexperia is a 16-bit BiCMOS buffer/line driver with integrated 30 Ω series termination resistors, 3-state outputs, four independent output-enable controls (1OE–4OE), ±32 mA sink/source drive capability, and IOFF partial power-down protection. It operates across 4.5 V to 5.5 V and supports -40 °C to +85 °C ambient conditions, commonly deployed in high-speed backplane and bus interface applications requiring impedance-matched signal integrity.
For engineers reviewing the 74ABT162244DGG,512 datasheet, 74ABT162244DGG,512 pinout, 74ABT162244DGG,512 application, or 74ABT162244DGG,512 equivalent, key selection criteria include its quad 4-bit configurable buffering, 30 Ω on-die series termination for reduced stub reflections, IOFF-enabled hot-swap compatibility, and TSSOP48 package suitability for dense PCB layouts.
Technical Context
The device implements four independent 4-bit non-inverting buffers, each controlled by a dedicated active-low output enable (1OE–4OE). Each buffer section drives four outputs with matched 30 Ω series resistors to minimize transmission line reflections in parallel bus environments.
Its BiCMOS architecture delivers TTL-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V) and fast propagation delays (tPLH/tPHL ≤ 2.7 ns at 5.0 V), while IOFF circuitry ensures <±100 μA power-off leakage when VCC = 0 V and inputs/outputs are biased up to 4.5 V - enabling safe partial power-down in mixed-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 4.5 V to 5.5 V - compatible with standard 5 V TTL and CMOS logic rails without level-shifting. |
| Output drive | +12 mA / -32 mA - sufficient to drive unterminated 50 Ω loads or fan out to multiple TTL inputs. |
| Propagation delay | 1.0–2.7 ns (tPLH/tPHL) - enables >350 MHz data rates in point-to-point or short-bus configurations. |
| Termination resistance | 30 Ω series per output - reduces overshoot/ringing on FR-4 traces up to ~10 cm without external resistors. |
| IOFF leakage | ±100 μA max at VCC = 0 V - prevents backflow current during live insertion or partial system power-down. |
| Operating temperature | -40 °C to +85 °C - qualified for industrial-grade embedded control and communications equipment. |
| ESD rating | HBM >2000 V, CDM >1000 V - robust enough for manual handling and board-level assembly without special ESD controls. |
Pinout & Package
TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm lead pitch, exposed thermal pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE, 3OE, 4OE (pins 1, 48, 25, 24) | Active-low output enable | Each controls 4 outputs independently; HIGH disables all 4 outputs into high-impedance state. |
| 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 (pins 43–47, 37–41, 32–36, 26–30) | Input terminals | Four groups of 4-bit non-inverting data inputs; electrically isolated per group for flexible bus partitioning. |
| 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 (pins 2–6, 8–12, 13–17, 19–23) | Output terminals | 16 buffered outputs, each with integrated 30 Ω series resistor; driven low/high or placed in 3-state. |
| VCC (pins 7, 18, 31, 42) | Power supply | Four distributed VCC pins reduce switching noise and improve decoupling effectiveness across the die. |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins provide low-inductance return paths and minimize ground bounce in high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 30 Ω series termination | Eliminates need for 16 discrete SMT resistors, saving PCB area and reducing BOM count in parallel bus interfaces. |
| IOFF partial power-down | Enables safe hot-plug operation and mixed-power-domain designs where VCC may be sequenced or powered off independently. |
| Quad independent 3-state control | Allows selective isolation of four 4-bit segments - e.g., isolating CPU address vs. data vs. control buses without global disable. |
| BiCMOS high-speed output stage | Delivers 32 mA sink current with sub-3 ns propagation delay, supporting clean edge rates on 50 Ω transmission lines. |
| Latch-up immunity | Exceeds 500 mA per JESD78B Class II Level A - ensures robustness against transient overvoltage events in noisy industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit terminated buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT162244DGGR | TSSOP48 package, identical electrical specs, same IOFF and termination; RoHS-compliant, tape-and-reel packaging variant. | No functional difference; differs only in packaging format (reel vs. tube) and reel quantity (2000 vs. 375). | Select for automated SMT production requiring full reel delivery and consistent placement feed. |
| 74LVCH162244APAG | Lower VCC range (1.65–3.6 V), no integrated termination, higher speed (tPD ≤ 2.1 ns), but lacks IOFF and 30 Ω resistors. | Suitable for low-voltage portable systems only; requires external termination and cannot support partial power-down. | Choose only if operating below 3.6 V and external termination is acceptable; not drop-in compatible for 5 V or hot-swap use. |
Compared with SN74ABT162244DGGR, the 74ABT162244DGG,512 offers identical performance but in tube packaging for prototyping or low-volume builds; versus 74LVCH162244APAG, it provides essential 5 V operation, built-in termination, and IOFF - making it the sole option for industrial backplane and hot-swap applications.

FAQ
Does the 74ABT162244DGG,512 support live insertion?
Yes. Its IOFF circuitry actively disables outputs and limits power-off leakage to ±100 μA when VCC = 0 V, preventing damaging backflow current during hot-swap events. This feature is verified per JESD78B Class II and enables safe insertion into powered backplanes without disrupting adjacent modules.
What is the purpose of the 30 Ω series termination resistors?
These resistors are integrated directly into each output path to match typical PCB trace impedances (40–60 Ω), suppressing signal reflections and overshoot on parallel buses up to ~10 cm in length. They eliminate the need for 16 discrete 30 Ω SMT resistors, reducing layout area and BOM count while improving signal fidelity.
Can this device operate at 3.3 V supply?
No. The 74ABT162244DGG,512 is specified only for 4.5 V to 5.5 V operation. Attempting 3.3 V supply violates recommended operating conditions and results in undefined logic thresholds, degraded drive strength, and potential failure to meet tPLH/tPHL timing specifications. Use LVCH or LVC variants for 3.3 V systems.
How many independent bus segments can be controlled?
Four. The device contains four separate 4-bit buffer sections (1A/1Y, 2A/2Y, 3A/3Y, 4A/4Y), each with its own active-low output enable (1OE–4OE). This allows independent 3-state control of four distinct 4-bit data paths - for example, isolating address, data, control, and status buses simultaneously.
