Product details
Overview
74ALVT162245DGG,11 from Nexperia is a 16-bit bidirectional bus transceiver with integrated 30 Ω series output termination resistors, dual 8-bit direction control (1DIR/2DIR), and dual active-low 3-state enables (1OE/2OE). It operates from 2.3 V to 3.6 V, supports 5 V I/O tolerance, delivers ±12 mA drive, and features bus-hold inputs eliminating external pull-ups. It is used in high-speed backplane and memory interface data routing where impedance-matched signal integrity is required.
For engineers reviewing the 74ALVT162245DGG,11 datasheet, 74ALVT162245DGG,11 pinout, 74ALVT162245DGG,11 application, or 74ALVT162245DGG,11 equivalent, key selection criteria include its 30 Ω on-die termination, dual independent 8-bit channel control, -40 °C to +85 °C industrial temperature range, BiCMOS process enabling TTL-level compatibility, and IOFF partial power-down capability.
Technical Context
The device implements two independent 8-bit transceiver channels, each with dedicated direction (DIR) and output enable (OE) signals, allowing asymmetric bidirectional data flow control. Its BiCMOS architecture combines bipolar speed with CMOS low power, enabling propagation delays as low as 0.5 ns (tPLH/tPHL at 3.3 V) and 3-state transition times under 5 ns.
Each output integrates a 30 Ω series resistor, matching typical PCB trace impedances to suppress reflections without external components. Bus-hold circuitry maintains valid logic states on unused I/O pins, and IOFF protection limits leakage current when VCC = 0 V, supporting live insertion and hot-swap operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.3 V to 3.6 V - Enables interoperability across 2.5 V and 3.3 V system domains. |
| I/O Voltage Tolerance | Inputs tolerant to 5.5 V - Allows direct interfacing with 5 V buses without level shifters. |
| Output Drive | ±12 mA - Sufficient to drive terminated transmission lines and multiple TTL loads. |
| Propagation Delay | 0.5 ns (min) at 3.3 V - Supports >200 MHz data rates in point-to-point or stubbed bus topologies. |
| Termination Resistance | 30 Ω series per output - Matches common FR-4 microstrip impedances, eliminating discrete termination. |
| Bus-Hold Current | ±75 μA (typ) - Actively retains last valid logic state on floating inputs, removing need for external pull-ups. |
| IOFF Leakage | ±100 μA max at VCC = 0 V - Prevents back-driving of powered subsystems during hot-plug events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVTH162245GR | TI part with identical 30 Ω termination, but wider VCC range (2.3–3.6 V same), higher drive (±24 mA), and no bus-hold. | Lacks bus-hold; requires external pull-ups on unused pins; better suited for high-fanout, low-noise environments. | Select when higher drive strength is needed and board space allows external biasing. |
| 74LVC162245ADGG,118 | Nexperia LVC variant: no integrated termination, lower drive (±24 mA), 1.65–3.6 V supply, no IOFF or bus-hold. | Requires external 30 Ω resistors and pull-ups; lacks hot-swap support; lower static power. | Select for cost-sensitive designs where termination and bus-hold are implemented externally. |
Compared with SN74ALVTH162245GR and 74LVC162245ADGG,118, the 74ALVT162245DGG,11 uniquely combines on-die 30 Ω termination, bus-hold, and IOFF in a single industrial-grade package-reducing component count and enabling robust hot-swap operation without sacrificing speed or voltage flexibility.

FAQ
What is the maximum clock/data rate supported by the 74ALVT162245DGG,11?
The device supports data rates exceeding 200 MHz, based on its minimum propagation delay of 0.5 ns (tPLH/tPHL at 3.3 V) and 3-state transition times under 5 ns. System-level timing depends on trace length, loading, and termination match-but the 30 Ω series resistor enables clean edge integrity up to 300 Mbps in controlled-impedance PCB environments.
Can the 74ALVT162245DGG,11 interface directly with 5 V microcontrollers?
Yes-the inputs are overvoltage tolerant to 5.5 V, allowing direct connection to 5 V logic outputs while the device operates at 2.3–3.6 V. Outputs are not 5 V-tolerant in drive mode, but the 5 V I/O compatibility specification confirms safe reception of 5 V signals without damage or level-shifting circuitry.
How does the bus-hold feature eliminate external pull-up resistors?
Internal bus-hold circuitry provides ±75 μA of active current to retain the last valid logic state on floating inputs. This holds unused or unterminated I/Os at defined HIGH or LOW levels without external components-verified across -40 °C to +85 °C and compliant with JEDEC JESD8-12 standards for bus-hold performance.
Is the 74ALVT162245DGG,11 suitable for hot-swap applications?
Yes-its IOFF circuitry limits power-off leakage to ±100 μA when VCC = 0 V, preventing back-current flow into unpowered sections. Combined with live-insertion-rated construction and ESD protection (HBM >2000 V), it meets industrial hot-swap requirements for modular backplane and field-replaceable unit designs.
