Product details
Overview
74ABT162245ADGG,11 from Nexperia is a 16-bit bidirectional bus transceiver with integrated 30 Ω series termination resistors, dual 8-bit direction control (1DIR/2DIR), independent 3-state enables (1OE/2OE), and IOFF partial power-down protection. It operates from 4.5 V to 5.5 V, delivers ±32 mA/±12 mA drive strength, and supports industrial temperature range (−40 °C to +85 °C). It is used in high-speed parallel bus interfaces between microcontrollers and peripheral ASICs or FPGAs.
For engineers reviewing the 74ABT162245ADGG,11 datasheet, 74ABT162245ADGG,11 pinout, 74ABT162245ADGG,11 application, or 74ABT162245ADGG,11 equivalent, key selection criteria include bidirectional 16-bit data path integrity, on-die 30 Ω termination for signal integrity at >100 MHz, IOFF-enabled hot-swap capability, and TSSOP48 package compatibility with dense PCB layouts.
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 data flow control. Its BiCMOS output stage combines bipolar speed (typ. 2.0 ns tPLH) with CMOS input compatibility and TTL-level interfacing.
The integrated 30 Ω series resistors are placed on all 32 I/O pins (A/B ports), reducing external component count and improving impedance matching on FR-4 traces. The IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ±100 μA and enabling safe live-insertion in powered-backplane systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Pinout & Package
TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm lead pitch, 1.2 mm max height - optimized for automated placement and thermal dissipation in space-constrained boards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Active-HIGH logic selects A→B (DIR=H) or B→A (DIR=L) per 8-bit block |
| 1OE, 2OE | Output enable input | Active-LOW - drives corresponding 8-bit port into high-impedance state when HIGH |
| 1A0–1A7, 2A0–2A7 | Data I/O (Port A) | First and second 8-bit bidirectional bus segment - connects to controller-side signals |
| 1B0–1B7, 2B0–2B7 | Data I/O (Port B) | First and second 8-bit bidirectional bus segment - connects to peripheral-side signals |
| VCC (Pins 7, 18, 31, 42) | Power supply | Four distributed VCC pins minimize switching noise and IR drop across high-current transitions |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight GND pins provide low-inductance return paths for all 32 I/Os and reduce ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit control | Separate 1DIR/1OE and 2DIR/2OE allow asymmetric read/write timing and selective port isolation |
| On-die 30 Ω series termination | Eliminates 32 external resistors, reduces layout area by >12 mm², and improves signal rise/fall monotonicity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bidirectional bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT162245DGGR | Same function and pinout; TI version uses different BiCMOS process - slightly higher ICC (0.7 mA vs 0.3 mA) and lower ESD rating (HBM 2000 V vs 2000 V, but CDM unspecified) | Valid for drop-in replacement where TI qualification and documentation ecosystem is required; not recommended for CDM-sensitive production lines | Select if TI's support infrastructure (SPICE models, reference designs) is prioritized over Nexperia's tighter CDM spec and lower static current. |
| 74LVTH162245ADGG,11 | Lower voltage (3.3 V only); 24 mA/−24 mA drive; no integrated termination; bus-hold enabled by default | Suitable for 3.3 V-only systems with external termination and where unused inputs require automatic hold without pull-ups | Choose only for 3.3 V domains requiring bus-hold; not interoperable with 5 V buses or for termination-critical 5 V applications. |
Compared with SN74ABT162245DGGR, the 74ABT162245ADGG,11 offers superior CDM robustness (1000 V vs unspecified) and lower quiescent current (0.3 mA vs 0.7 mA), while the 74LVTH162245ADGG,11 trades termination and voltage flexibility for 3.3 V efficiency and bus-hold - making it unsuitable for 5 V or termination-dependent designs.

FAQ
Does 74ABT162245ADGG,11 support hot-swap without external circuitry?
Yes. Its IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±100 μA. This allows safe insertion into live 5 V backplanes without external power sequencing or isolation FETs - verified per JESD78 Class II Level B latch-up testing.
Can the 30 Ω termination resistors be bypassed for non-terminated applications?
No. The 30 Ω resistors are monolithically integrated in series with each I/O pin and cannot be disabled or shorted. For non-terminated use, select the 74ABT162244ADGG,11 (non-terminated version) or use external series resistors with this device only if trace impedance exceeds 30 Ω.
What is the maximum clock rate supported for reliable 16-bit data transfer?
Based on worst-case propagation delay (3.5 ns tPLH/tPHL) and 3-state disable time (7.0 ns tPZL), the device supports sustained 100 MHz bus cycles with 5 ns setup/hold margin. At 133 MHz (PCI-X), layout-controlled trace length and termination must be validated per IBIS simulation.
How does the dual OE/DIR architecture improve system timing control?
Independent 1OE/2OE and 1DIR/2DIR inputs allow staggered enable/disable and direction reversal across the two 8-bit segments - enabling pipelined read/write operations, burst-mode handshaking, and reduced bus turnaround latency in multi-master systems without external glue logic.
