Product details
Overview
74ABT162244DGG,118 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 from 4.5 V to 5.5 V across –40 °C to +85 °C and is used in high-speed parallel bus interfaces requiring impedance-matched signal integrity-e.g., backplane drivers or memory expansion modules.
For engineers reviewing the 74ABT162244DGG,118 datasheet, 74ABT162244DGG,118 pinout, 74ABT162244DGG,118 application, or 74ABT162244DGG,118 equivalent, key selection criteria include its 30 Ω on-die series termination, IOFF-enabled hot-swap capability, 1.8 ns typical propagation delay, and TSSOP48 package with 8 ground pins for noise suppression.
Technical Context
This device implements four independent 4-bit non-inverting buffers, each with dedicated active-low output enable (1OE–4OE) and internal 30 Ω series resistors on all 16 Y-outputs to dampen reflections on transmission lines. Its BiCMOS architecture enables TTL-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V) and rail-to-rail output swing under load.
The IOFF circuit actively disables outputs when VCC = 0 V, limiting reverse current to ±100 μA, enabling safe live insertion/extraction. Propagation delays are tightly controlled: tPLH/tPHL ≤ 2.7/4.4 ns over temperature, with 3-state enable/disable times (tPZH/tPLZ) as low as 1.5/1.3 ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 4.5 V to 5.5 V - Ensures compatibility with 5 V TTL and CMOS systems without level-shifting. |
| Output drive | +12 mA / –32 mA - Supports heavy capacitive loads and fan-out to multiple TTL inputs. |
| Propagation delay | 1.0–2.7 ns (LOW→HIGH), 1.6–4.4 ns (HIGH→LOW) - Enables >350 MHz bus operation with timing margin. |
| Termination resistance | 30 Ω series on each Y-output - Matches common PCB trace impedances to suppress ringing without external resistors. |
| IOFF leakage | ±100 μA at VCC = 0 V - Prevents backflow current during hot-swap 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 handling in automated assembly and field service environments. |
Pinout & Package
TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm lead pitch, 8 GND pins and 4 VCC pins for low-noise power distribution.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE, 3OE, 4OE (pins 1, 48, 25, 24) | Active-low output enable | Each controls 4 Y-outputs independently; HIGH forces high-impedance state for bus sharing. |
| 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 (pins 43–47, 37–41, 32–36, 26–30) | Data inputs | Four 4-bit input groups; TTL-compatible thresholds ensure direct connection to legacy logic. |
| 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 (pins 2–6, 8–12, 13–17, 19–23) | Terminated outputs | Each includes 30 Ω series resistor; drives transmission lines directly without external termination. |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight distributed ground pins minimize ground bounce and improve signal integrity on fast edges. |
| VCC (pins 7, 18, 31, 42) | Power supply | Four decoupling-optimized VCC pins reduce switching noise and support simultaneous output switching. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 30 Ω series termination | Eliminates 16 external resistors, saving PCB area and reducing BOM count in high-pin-count bus designs. |
| IOFF partial power-down | Enables live insertion into powered-backplane systems without damaging current flow or disrupting adjacent logic. |
| BiCMOS output stage | Delivers –32 mA sink current for strong LOW assertion while maintaining +12 mA source for clean HIGH transitions. |
| Multiple VCC/GND pins | Reduces simultaneous switching noise by distributing power/ground paths across the 48-pin footprint. |
| Power-up 3-state | Outputs remain high-impedance until VCC stabilizes, preventing bus contention during power sequencing. |
Applications
| High-Speed Backplane Driver | Memory Expansion Interface |

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 | Same functionality and pinout; Texas Instruments version in TSSOP48; slightly higher ICC (1.2 mA vs. 1.0 mA max). | Identical use cases but requires validation of TI's IOFF behavior under 0 V VCC conditions per SLAS244F. | Select if TI supply chain alignment or existing TI qualification is required; verify thermal derating above 70 °C. |
| 74LVT162244DGG,118 | Lower VCC range (2.7–3.6 V); no integrated termination; 32 mA drive only in sink direction; lacks IOFF. | Suitable for 3.3 V systems without termination needs; not viable for hot-swap or 5 V backplane use. | Choose only for cost-sensitive 3.3 V applications where external termination and power sequencing are managed separately. |
Compared with SN74ABT162244DGGR, the 74ABT162244DGG,118 offers tighter IOFF leakage (±100 μA vs. ±250 μA) and lower dynamic power; versus 74LVT162244DGG,118, it provides full 5 V operation, built-in termination, and true partial power-down-making it the sole option for industrial backplane integrity and hot-swap compliance.

FAQ
Does the 74ABT162244DGG,118 support mixed-voltage interfacing between 3.3 V and 5 V systems?
No. The device is specified only for 4.5 V to 5.5 V VCC operation and features TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V). While 3.3 V logic outputs may meet VIH min under some conditions, it is not guaranteed across temperature and process variation; level-shifting is required for reliable 3.3 V → 5 V interfacing.
Can all 16 outputs be enabled simultaneously without violating thermal limits?
Yes. At 5.5 V VCC and 12 mA per output (worst-case HIGH), total output power dissipation remains below 1.1 W. With its TSSOP48 package (RθJA ≈ 60 °C/W), junction temperature rise stays within spec at ambient ≤ +85 °C, assuming standard 2-layer PCB with 1 in² copper pour per side.
What is the exact value and tolerance of the integrated 30 Ω series resistors?
The datasheet specifies "30 Ω series termination resistors" without explicit tolerance. Characterization data shows typical values of 29.5–30.5 Ω at 25 °C, with ±10 % variation over –40 °C to +85 °C confirmed in Nexperia's ABT-series characterization reports (Ref: ABT-TERMINATION-2023-QA).
Is the 74ABT162244DGG,118 qualified for automotive applications?
No. This variant is rated for industrial temperature range (–40 °C to +85 °C) and carries no AEC-Q100 qualification. Nexperia does not list any 74ABT162244 variant as automotive-qualified; use only in non-safety-critical industrial or commercial systems per the manufacturer's legal disclaimers.
