Product details
Overview
74ABT162245ADL,118 from Nexperia is a 16-bit bidirectional bus transceiver with integrated 30 Ω series termination resistors, 3-state outputs, and dual independent direction/enable control (1DIR/2DIR, 1OE/2OE). It operates from 4.5 V to 5.5 V, delivers ±32 mA sink/source drive, supports -40 °C to +85 °C ambient, and features IOFF partial power-down protection. It is used in high-speed parallel bus interfaces between microcontrollers and peripheral ASICs or FPGAs.
For engineers reviewing the 74ABT162245ADL,118 datasheet, 74ABT162245ADL,118 pinout, 74ABT162245ADL,118 application, or 74ABT162245ADL,118 equivalent, key selection criteria include bidirectional 16-bit data path partitioning, on-die 30 Ω termination for signal integrity, TTL-level compatibility, IOFF-enabled hot-swap capability, and TSSOP48 thermal/power performance under 5 V operation.
Technical Context
This device implements two independent 8-bit transceiver blocks sharing no internal logic coupling-each with dedicated DIR and OE inputs enabling asymmetric bus control. The BiCMOS output stage provides fast propagation (1.0–4.9 ns) and robust drive (+12 mA / –32 mA), while the IOFF circuit actively disables outputs during VCC ramp-down to prevent backflow current.
The integrated 30 Ω series resistors are placed directly at each output terminal, reducing external component count and improving impedance matching on PCB traces up to 100 MHz. Unlike standard ABT transceivers, this variant lacks bus-hold functionality-requiring external pull-ups on unused inputs if floating-state immunity is needed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74ABTH162245ADGG | Includes bus-hold inputs (IBHL/IBHH specified); same pinout, timing, and termination | Eliminates need for external pull-ups on unused inputs; improves floating-input noise immunity | Select when system has unterminated or high-impedance data lines prone to noise-induced glitches |
| SN74LVC16245ADGGR | 3.3 V only (1.65–3.6 V); no integrated termination; lower drive (±24 mA); different pinout | Requires external 30 Ω resistors and level-shifting for 5 V systems; suited for low-voltage portable designs | Select only for 3.3 V-native systems where power efficiency outweighs board space and signal-integrity benefits of integrated termination |
Compared with 74ABTH162245ADGG, the 74ABT162245ADL,118 trades bus-hold immunity for reduced input leakage and simpler biasing; versus SN74LVC16245ADGGR, it offers native 5 V operation, higher drive, and built-in termination-making it optimal for industrial backplanes where signal integrity and voltage compatibility are critical.

FAQ
Is 74ABT162245ADL,118 pin-compatible with 74ABTH162245ADGG?
Yes-both devices use identical TSSOP48 (SOT362-1) packaging and share identical pin assignments, electrical timing, supply range, and termination values. The sole functional difference is the absence of bus-hold circuitry in the 74ABT variant, confirmed by Nexperia's ordering table and pin description sections.
Does 74ABT162245ADL,118 support hot-swap without external protection?
Yes-the integrated IOFF circuitry actively disables all outputs when VCC drops below ~0.8 V, limiting back-current to ≤100 μA (per datasheet Table 6, IOFF parameter). This meets JEDEC JESD78 Class II Level B latch-up immunity and enables safe insertion into powered backplanes without auxiliary protection diodes.
What is the maximum recommended trace length for reliable operation with integrated 30 Ω termination?
At 100 MHz, the integrated 30 Ω resistors match typical FR-4 microstrip impedance (Z₀ ≈ 50–70 Ω) when combined with driver output impedance (~15–20 Ω), enabling clean signal integrity on traces up to 15 cm. For longer runs or higher frequencies, verify eye diagram compliance using the test conditions in Figure 6 and Table 9 of the datasheet.
Can 74ABT162245ADL,118 be used in mixed-voltage systems with 3.3 V controllers?
No-it is specified only for 4.5 V to 5.5 V operation and lacks 3.3 V tolerance on inputs. Driving its inputs from 3.3 V logic violates the VIH minimum (2.0 V) but risks marginal noise margins and undefined behavior at temperature extremes. A level-shifting solution or 3.3 V–compatible transceiver like SN74LVC16245A is required for true mixed-voltage interoperability.
