Product details
Overview
74ABT162244DL,118 from Nexperia is a 16-bit BiCMOS buffer/line driver with integrated 30 Ω series termination resistors, 3-state outputs, and four independent output-enable controls (1OE–4OE). It operates from 4.5 V to 5.5 V, delivers ±32 mA/±12 mA drive capability, and supports partial power-down via IOFF circuitry. It is used in high-speed parallel bus interfaces requiring impedance-matched signal integrity, such as backplane drivers and memory address/data buffers.
For engineers reviewing the 74ABT162244DL,118 datasheet, 74ABT162244DL,118 pinout, 74ABT162244DL,118 application, or 74ABT162244DL,118 equivalent, this page provides verified functional architecture, TSSOP48 package mapping, propagation delay specs (1.0–4.4 ns), IOFF-enabled power sequencing behavior, and real-world use cases in industrial control backplanes and legacy bus systems.
Technical Context
The device implements four independent 4-bit buffered channels, each with dedicated low-active output enable (1OE–4OE) controlling four 3-state outputs. Each channel features internal 30 Ω series termination on all Y outputs, enabling direct connection to 50 Ω transmission lines without external resistors.
Its BiCMOS process delivers TTL-compatible input thresholds (VIL ≤ 0.8 V, VIH ≥ 2.0 V), fast propagation delays (tPLH/tPHL typ. 1.8/3.2 ns at VCC = 5.0 V), and robust IOFF protection that disables outputs and limits backflow current during partial power-down - critical for hot-swap and mixed-voltage system designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL and CMOS logic rails. |
| Output Drive | +12 mA / –32 mA - supports driving heavy capacitive loads and fan-out to multiple inputs. |
| Propagation Delay | tPLH = 1.0–2.7 ns, tPHL = 1.6–4.4 ns - enables >300 MHz bus operation with tight timing margins. |
| IOFF Leakage | ±5.0 μA max at VCC = 0 V - prevents damaging back-current when powered down while inputs remain active. |
| Operating Temp | –40 °C to +85 °C - qualified for industrial ambient environments without derating. |
| ESD Protection | HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events per JEDEC JS-001/JS-002. |
| Termination | 30 Ω series resistor on each Y output - matches typical PCB trace impedance for reduced reflections on 50 Ω lines. |
Pinout & Package
TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm pitch, lead finish matte tin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE, 2OE, 3OE, 4OE (Pins 1, 48, 25, 24) | Low-active output enable | Each controls 4 Y outputs; HIGH forces high-impedance state - enables independent channel gating. |
| 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 (Pins 43–47, 37–41, 32–36, 26–30) | Input data terminals | Four groups of 4-bit inputs feeding respective buffer sections - supports flexible partitioning (1×16, 2×8, or 4×4). |
| 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 (Pins 2–6, 8–12, 13–17, 19–23) | Output data terminals | 3-state outputs with integrated 30 Ω series termination - eliminates need for discrete series resistors on PCB. |
| VCC (Pins 7, 18, 31, 42) | Power supply | Four distributed VCC pins reduce switching noise and improve power delivery integrity across wide bus. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins minimize ground bounce and ensure stable return paths for all 16 outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 30 Ω series termination | Eliminates eight external resistors per device in point-to-point or daisy-chained bus topologies. |
| IOFF partial power-down protection | Prevents destructive back-current flow when VCC = 0 V but input signals remain active - essential for hot-swap systems. |
| Multiple VCC/GND pins | Reduces simultaneous switching noise (SSN) by distributing power/ground connections across die corners. |
| BiCMOS high-speed architecture | Combines bipolar speed and CMOS low static power - achieves sub-3 ns propagation with <1 mA ICC in 3-state mode. |
| Latch-up immunity | Exceeds 500 mA per JESD78B Class II - ensures robustness against transient overvoltage events. |
Applications
| Industrial Backplane Interface | Legacy Memory Address Buffer |

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 function, identical pinout, same TSSOP48 package, but TI version lacks IOFF specification and has higher ICC (1.5 mA vs 1.0 mA max). | Not suitable for partial power-down systems; requires external isolation for hot-swap. | Select only if IOFF is not required and TI supply chain preference exists. |
| 74LVT162244DGG | Lower VCC range (2.7–3.6 V), no internal termination, 32 mA drive, but lacks 30 Ω resistors and IOFF. | Requires external 33 Ω series resistors and cannot be safely powered down mid-bus activity. | Choose only for 3.3 V-only systems where termination is added externally and power sequencing is fully controlled. |
Compared with SN74ABT162244DGGR and 74LVT162244DGG, the 74ABT162244DL,118 uniquely combines 5 V operation, integrated 30 Ω termination, and IOFF - making it the only option for industrial hot-swap backplanes needing both signal integrity and safe power-down behavior.

FAQ
Does 74ABT162244DL,118 support mixed-voltage operation between input and output sides?
No. The device operates strictly at a single VCC rail (4.5–5.5 V) and does not support level translation. Inputs are TTL-compatible (VIH ≥ 2.0 V, VIL ≤ 0.8 V), and outputs swing rail-to-rail within the same VCC domain. It cannot interface 3.3 V logic directly without external level-shifting circuitry.
Can the 30 Ω internal termination resistors be bypassed or disabled?
No. The 30 Ω series resistors are monolithically integrated into each Y output path and cannot be disconnected or configured. They are always present when the output is active (nOE = LOW); no register, fuse, or external control alters their presence or value.
What is the maximum sustained output current per Y pin during continuous HIGH or LOW states?
Per datasheet Table 7, the absolute maximum DC output current is –64 mA (HIGH) and +128 mA (LOW) - but these are short-duration limiting values. For continuous operation, the recommended limit is –32 mA (HIGH) and +12 mA (LOW) at TA = 85 °C to maintain thermal stability and avoid exceeding junction temperature limits.
Is 74ABT162244DL,118 qualified for automotive applications?
No. This part is specified for industrial temperature range (–40 °C to +85 °C) and carries no AEC-Q100 qualification. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products are not tested or warranted for automotive use - including engine control, ADAS, or infotainment systems.
