Product details
Overview
74LVTH16245BDGG:11 from Nexperia is a 3.3 V, 16-bit bidirectional bus transceiver with 3-state outputs, dual direction control (1DIR/2DIR), dual output enables (1OE/2OE), and bus-hold inputs eliminating external pull-ups. It operates from -40 °C to +85 °C with ±64 mA sink/source drive and 5.5 V overvoltage-tolerant inputs, used in high-speed backplane and memory interface data routing.
For engineers reviewing the 74LVTH16245BDGG:11 datasheet, 74LVTH16245BDGG:11 pinout, 74LVTH16245BDGG:11 application, or 74LVTH16245BDGG:11 equivalent, key selection criteria include 3.3 V supply compatibility, 2.7–3.6 V operating range, 3.3 ns max propagation delay, bus-hold functionality, and TSSOP48 package thermal and layout constraints.
Technical Context
This BiCMOS transceiver implements two independent 8-bit bidirectional data paths, each controlled by dedicated DIR and OE signals. Its bus-hold circuitry maintains valid logic states on unused inputs without external resistors, enabling robust hot-swap operation.
It supports live insertion/extraction and features IOFF circuitry for partial power-down mode when VCC = 0 V. Input clamping protects against overvoltage up to 7.0 V, while output drive capability (+64 mA sink / –32 mA source) ensures TTL-level interfacing and 5 V bus compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 3.6 V - Enables stable operation across industrial-grade 3.3 V rail tolerances. |
| Propagation Delay | 1.0–3.3 ns (VCC = 3.0–3.6 V) - Supports >200 MHz data transfer in point-to-point or stub-bus topologies. |
| Output Drive | +64 mA sink / –32 mA source - Drives heavy capacitive loads and interfaces directly with 5 V TTL systems. |
| Input Voltage Range | 0 V to 5.5 V - Allows mixed-voltage system interfacing without level shifters. |
| Bus-Hold Current | ±75–135 μA - Maintains defined logic state on floating inputs, removing need for external pull-up/pull-down resistors. |
| Operating Temperature | –40 °C to +85 °C - Qualified for industrial ambient environments without derating. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Ensures robust handling during PCB assembly and field service. |
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 high-density PCB layouts with enhanced thermal dissipation vs. SOIC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR (Pins 1, 24) | Direction control input | Active-HIGH signal selecting data flow direction per 8-bit port (A→B or B→A). |
| 1OE, 2OE (Pins 48, 25) | Output enable input (active LOW) | Independent 3-state control for each 8-bit port; HIGH forces high-impedance output. |
| 1A0–1A7 (Pins 47, 46, 44, 43, 41, 40, 38, 37) | Data I/O port A (side 1) | First 8-bit bidirectional bus segment; connects to local controller or memory subsystem. |
| 1B0–1B7 (Pins 2, 3, 5, 6, 8, 9, 11, 12) | Data I/O port B (side 1) | Second 8-bit bidirectional bus segment; interfaces to peripheral or expansion bus. |
| 2A0–2A7 (Pins 36, 35, 33, 32, 30, 29, 27, 26) | Data I/O port A (side 2) | Third 8-bit bidirectional bus segment; supports dual-port memory or parallel I/O expansion. |
| 2B0–2B7 (Pins 13, 14, 16, 17, 19, 20, 22, 23) | Data I/O port B (side 2) | Fourth 8-bit bidirectional bus segment; enables full 16-bit or split 8+8 bus bridging. |
| VCC (Pins 7, 18, 31, 42) | Power supply | Four distributed supply pins reduce IR drop and improve noise immunity across wide bus. |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight ground pins provide low-inductance return paths, critical for signal integrity at high speed. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit transceivers | Enables flexible bus partitioning: one 16-bit path or two isolated 8-bit channels with separate DIR/OE control. |

| 74ALVC16245PW,118 | Same 2.3–3.6 V range, ±24 mA drive, no bus-hold, no IOFF, TSSOP48 | Lacks overvoltage tolerance and bus-hold; requires external pull-ups and level-shifting for 5 V interfaces | Choose only for space-constrained designs where 5 V compatibility is absent and BOM simplicity is secondary. |
Compared with SN74LVC16245ADGGR and 74ALVC16245PW,118, the 74LVTH16245BDGG:11 delivers superior 5 V input tolerance, stronger drive, built-in bus-hold, and IOFF - making it the only option qualified for mixed-voltage, hot-swap, and high-noise industrial backplane use.

FAQ
What is the maximum clock frequency supported by the 74LVTH16245BDGG:11?
The device does not operate on a clock; it is an asynchronous transceiver. Its 3.3 ns max propagation delay (at VCC = 3.0–3.6 V) supports reliable data transfer rates exceeding 200 MHz in point-to-point configurations, limited only by system-level setup/hold timing and PCB trace length.
Can the 74LVTH16245BDGG:11 be used with a 5 V supply?
No - the absolute maximum VCC is +4.6 V, but recommended operation is strictly 2.7–3.6 V. However, its inputs tolerate up to 5.5 V, allowing safe connection to 5 V buses while powered from 3.3 V, eliminating level shifters in mixed-voltage systems.
How does the bus-hold feature affect power consumption?
Bus-hold draws ±75–135 μA per enabled input at VCC = 3 V, adding negligible static current (<1 mA total for all 32 data pins). It eliminates external pull-up resistors, reducing overall system power and board area without compromising signal integrity on unterminated lines.
Is the 74LVTH16245BDGG:11 pin-compatible with the 74LVT16245BDGG?
Yes - both share identical TSSOP48 (SOT362-1) pinout, function table, and AC/DC specifications. The 'H' suffix denotes enhanced drive strength and improved ESD performance (HBM >2000 V), making it a direct, higher-performance drop-in replacement for legacy 74LVT16245B designs.
