Product details
Overview
74ABT162244DL,112 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 output drive, and supports partial power-down via IOFF circuitry. It is used in high-speed parallel bus interfaces requiring controlled impedance and hot-swap capability.
For engineers reviewing the 74ABT162244DL,112 datasheet, 74ABT162244DL,112 pinout, 74ABT162244DL,112 application, or 74ABT162244DL,112 equivalent, key selection criteria include its 30 Ω on-die termination, IOFF-enabled partial power-down, -40 °C to +85 °C industrial temperature range, and TSSOP48 package compatibility with dense PCB layouts.
Technical Context
This device implements four independent 4-bit non-inverting buffers, each with dedicated active-low output enable (1OE–4OE) and 30 Ω series source termination per output. Its BiCMOS architecture enables TTL-level input compatibility and fast propagation delays (tPLH/tPHL ≤ 2.7 ns at 5.0 V).
The IOFF circuit ensures outputs enter high-impedance state when VCC = 0 V, blocking backflow current during live insertion or system power sequencing. Multiple VCC/GND pairs reduce switching noise, and ESD protection meets HBM >2000 V and CDM >1000 V standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures robust operation across industrial 5 V rail tolerances. |
| Output Drive | +12 mA / -32 mA - Supports driving terminated transmission lines and fan-out to multiple TTL loads. |
| Propagation Delay | tPLH ≤ 2.7 ns, tPHL ≤ 4.4 ns @ 5.0 V - Enables reliable operation in >300 MHz bus systems. |
| Termination Resistance | 30 Ω series per output - Matches common PCB trace impedances to suppress reflections without external resistors. |
| IOFF Leakage | ±100 μA @ VCC = 0 V - Prevents damaging back-current during hot-plug or partial power-down sequences. |
| Operating Temperature | -40 °C to +85 °C - Qualified for industrial-grade embedded control and communications equipment. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets JEDEC JS-001/JS-002 for handling and board-level reliability. |
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) | Active-low output enable | Each controls 4 outputs independently; HIGH disables all 4 outputs into high-Z state. |
| 1A0–1A3, 2A0–2A3, 3A0–3A3, 4A0–4A3 (Pins 47,46,44,43; 41,40,38,37; 36,35,33,32; 30,29,27,26) | Data inputs | Four 4-bit input groups; routed to corresponding output banks with no internal cross-talk. |
| 1Y0–1Y3, 2Y0–2Y3, 3Y0–3Y3, 4Y0–4Y3 (Pins 2,3,5,6; 8,9,11,12; 13,14,16,17; 19,20,22,23) | Buffered outputs | Non-inverting outputs each with integrated 30 Ω series resistor; support point-to-point or multidrop bus topologies. |
| VCC (Pins 7, 18, 31, 42) | Power supply | Four distributed VCC pins minimize IR drop and supply noise across high-speed switching activity. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins provide low-inductance return paths and reduce ground bounce in 16-bit parallel operation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 30 Ω series termination | Eliminates need for 16 discrete 30 Ω SMT resistors, reducing BOM count and layout area by ~25 mm². |
| IOFF partial power-down | Enables safe live insertion into powered backplanes without risk of latch-up or bus contention. |
| Multiple VCC/GND pairs | Reduces simultaneous switching noise (SSN) by distributing supply/return currents across 4 VCC and 8 GND pins. |
| BiCMOS output stage | Delivers -32 mA sink current while maintaining TTL-compatible input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V). |
| Power-up 3-state | Outputs remain in high-impedance until VCC stabilizes, preventing bus glitches during power-on reset sequences. |
Applications

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 and pinout; TI version uses different BiCMOS process, resulting in slightly higher ICC (1.2 mA vs 1.0 mA max) and lower ESD rating (HBM 2000 V vs 2000 V, but CDM only 500 V). | Not qualified for hot-swap in high-reliability backplanes due to reduced CDM immunity. | Select if TI ecosystem alignment or existing TI qualification is required; verify CDM margin in live-insertion use cases. |
| 74LVT162244DGG | Lower voltage operation (2.7–3.6 V), no integrated termination, IOFF not supported, and reduced drive (-24 mA / +24 mA). | Requires external 30 Ω resistors and cannot be used in partial-power-down systems. | Choose only for 3.3 V-only systems where cost reduction outweighs termination integration and IOFF benefits. |
Compared with SN74ABT162244DGGR and 74LVT162244DGG, the 74ABT162244DL,112 uniquely combines 30 Ω on-die termination, IOFF, and full 5 V industrial specs in one TSSOP48 package-enabling compact, robust, and hot-swap-capable bus interface designs without design compromises.

FAQ
What is the purpose of the 30 Ω series termination resistors in the 74ABT162244DL,112?
The 30 Ω resistors are integrated into each output path to match typical PCB trace impedances (e.g., 50–75 Ω single-ended), suppressing signal reflections and ringing without requiring external components. This improves signal integrity in high-speed parallel buses up to 300 MHz and reduces layout complexity and BOM count.
Does the 74ABT162244DL,112 support hot-plug or live insertion?
Yes-it supports live insertion via its IOFF circuitry, which disables outputs and limits leakage to ±100 μA when VCC = 0 V. This prevents back-current flow into powered systems during module replacement, satisfying requirements for modular backplane and PLC I/O architectures.
How many independent output-enable controls does the 74ABT162244DL,112 have, and how are they assigned?
It has four active-low output enables: 1OE (Pin 1), 2OE (Pin 48), 3OE (Pin 25), and 4OE (Pin 24). Each controls a distinct 4-bit output group (1Y0–1Y3, 2Y0–2Y3, etc.), enabling flexible segmentation of the 16-bit bus for partial activation or test-mode isolation.
Can the 74ABT162244DL,112 operate reliably at 4.5 V supply voltage?
Yes-the device is fully specified from 4.5 V to 5.5 V. At 4.5 V, it maintains guaranteed output drive (-32 mA sink, +12 mA source), propagation delay (tPHL ≤ 4.4 ns), and input thresholds (VIH ≥ 2.5 V, VIL ≤ 0.8 V), making it suitable for systems with aging or loosely regulated 5 V rails.
