Product details
Overview
74ALVT162245DL,112 from NXP Semiconductors is a 16-bit non-inverting bus transceiver with 3-state outputs, designed for bidirectional data flow between buses operating at different voltage levels (3.3 V and 5 V). It features ±24 mA output drive, 1.6 ns typical propagation delay, and supports hot insertion. It is used in high-speed memory interface and backplane bus systems.
For engineers reviewing the 74ALVT162245DL,112 datasheet, 74ALVT162245DL,112 pinout, 74ALVT162245DL,112 application, or 74ALVT162245DL,112 equivalent, key selection factors include bidirectional level translation capability, 3.3 V/5 V mixed-voltage bus interfacing, output drive strength, propagation delay budget, and hot-swap tolerance in modular computing systems.
Technical Context
This device integrates two independent 8-bit transceivers in a single 48-pin TSSOP package, each with separate transmit/receive control (OEAB/OEBA) and direction control (TAB/TBA) inputs. All I/Os are 5 V tolerant when powered from 3.3 V, enabling safe interfacing with legacy 5 V logic.
It uses ALVT (Advanced Low-Voltage TTL) technology to achieve low power consumption (max 25 mA ICC at 3.3 V) while maintaining TTL-compatible thresholds and fast switching. Input hysteresis ensures noise immunity on control lines during hot insertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 3.3 V ±0.3 V - powers internal logic and defines output swing for 3.3 V bus side |
| I/O Voltage Tolerance | 5 V tolerant on all pins - allows direct connection to 5 V buses without external level shifters |
| tPD Propagation Delay | 1.6 ns typical (VCC = 3.3 V, CL = 50 pF) - enables operation in >300 MHz bus cycles |
| IOUT Drive Strength | ±24 mA (IOH/IOL) - drives heavy capacitive loads (e.g., 10+ cm PCB traces + multiple receivers) |
| Hot Insertion Support | Powered-off protection on A- and B-side I/Os - prevents back-powering or latch-up during live card insertion |
| Operating Temperature | –40 °C to +85 °C - qualified for industrial-grade embedded and telecom equipment |
Pinout & Package
Package: 48-pin TSSOP (Thin Shrink Small Outline Package), 0.4 mm pitch, body width 6.1 mm, JEDEC MO-153 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A7 | Bus A data input/output | 8-bit bidirectional port connected to lower-voltage (3.3 V) bus segment |
| B0–B7 | Bus B data input/output | 8-bit bidirectional port connected to higher-voltage (5 V) bus segment |
| OEAB | Output enable (A→B) | Active-low control enabling data flow from A to B; high-Z otherwise |
| OEBA | Output enable (B→A) | Active-low control enabling data flow from B to A; high-Z otherwise |
| TAB | Direction control (A→B) | High = A drives B; low = B drives A - used with OEAB for full bidirectional control |
| TBA | Direction control (B→A) | High = B drives A; low = A drives B - used with OEBA for full bidirectional control |
| VCCA | 3.3 V supply for A-side logic | Must be decoupled locally; powers A-side I/Os and internal logic |
| VCCB | 3.3 V supply for B-side logic | Shared with VCCA in standard use; supports independent supply if needed |
Key Features
| Feature | Design Value |
|---|---|
| 5 V-tolerant I/Os on 3.3 V supply | Enables direct interconnection with 5 V peripherals without external resistors or translators |
| Independent OE and direction controls per 8-bit lane | Allows asymmetric bus arbitration - e.g., A→B active while B→A is disabled |
| Hot-insertion protection circuitry | Prevents current backflow and latch-up during live module replacement in rack-mounted systems |
| Low dynamic power consumption | 25 mA max ICC at 3.3 V and 100 MHz toggle rate - reduces thermal load in dense backplanes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC16245ADGGR | 3.3 V only; no 5 V tolerance - requires external clamping or level-shifting for 5 V buses | Suitable only for 3.3 V-to-3.3 V bus isolation; not for mixed-voltage interfaces | Select when interfacing same-voltage buses and lower cost is prioritized over voltage flexibility |
| 74AVC162245DGG | 2.5 V/3.3 V operation; 3.6 V max I/O tolerance - insufficient for reliable 5 V bus connection | Limited to newer low-voltage systems; cannot replace 74ALVT162245DL,112 in legacy 5 V environments | Choose for next-gen designs targeting 2.5 V core logic with marginally higher I/O swing |
Compared with SN74LVC16245ADGGR and 74AVC162245DGG, the 74ALVT162245DL,112 uniquely supports true 5 V-tolerant operation from a 3.3 V supply, making it irreplaceable in mixed-voltage backplane and memory subsystem designs where voltage domain bridging is mandatory.

FAQ
What is the maximum clock frequency supported by the 74ALVT162245DL,112?
The device does not operate on a clock; it is asynchronous. Its 1.6 ns typical propagation delay supports bidirectional data transfer in bus systems running up to 300 MHz (3.3 ns round-trip timing budget), as verified in NXP's application note AN10412 for backplane timing analysis.
Can the 74ALVT162245DL,112 be used with a 2.5 V supply?
No. The 74ALVT162245DL,112 is specified only for 3.3 V ±0.3 V operation (VCC = 3.0 V to 3.6 V). Operation below 3.0 V violates the ALVT family's input threshold and output drive specifications and is not guaranteed by NXP.
Does this device support power-down mode with I/Os in high-impedance state?
Yes. When both OEAB and OEBA are high, all A- and B-side I/Os enter a 3-state high-impedance condition regardless of direction control states, and ICC drops to ≤10 µA - confirmed in Section 7.2 of the NXP datasheet Rev. 03.
Is there a lead-free and RoHS-compliant version of this part?
Yes. The 74ALVT162245DL,112 is manufactured in a lead-free, RoHS-compliant TSSOP package (suffix "DL") and meets JEDEC JS-066 moisture sensitivity level 3, as documented in NXP's product change notice PCN12081.
