Product details
Overview
74LVCH162245ADGG,1 from Nexperia is a 16-bit dual-directional bus transceiver with integrated 30 Ω series termination resistors, 5 V-tolerant I/O, and bus-hold on all data inputs. It operates from 1.2 V to 3.6 V supply, supports mixed-voltage translation between 3.3 V and 5 V systems, and features two independent direction (1DIR/2DIR) and output-enable (1OE/2OE) controls for flexible 8-bit or 16-bit data flow in high-speed memory and peripheral interfaces.
For engineers reviewing the 74LVCH162245ADGG,1 datasheet, 74LVCH162245ADGG,1 pinout, 74LVCH162245ADGG,1 application, or 74LVCH162245ADGG,1 equivalent, this device is selected for robust bidirectional bus interfacing where IOFF partial power-down, Schmitt-trigger noise immunity, and elimination of external pull-ups are required in industrial control backplanes and FPGA-to-ASIC interconnects.
Technical Context
This transceiver implements dual 8-bit flow-through architecture with separate DIR/OE pairs per byte lane, enabling independent control of data direction and 3-state output enable. Its IOFF circuitry actively disables outputs during power-down to prevent backflow current, while Schmitt-trigger inputs tolerate slow-rising signals common in legacy bus environments.
All 16 data I/Os feature bus-hold functionality (exclusive to LVCH variant), eliminating need for external pull-up resistors on unused or floating lines. The integrated 30 Ω series resistors dampen signal reflections on PCB traces up to 100 MHz, reducing EMI without requiring discrete termination components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - Enables operation across low-power microcontrollers and standard 3.3 V logic domains. |
| I/O Voltage Tolerance | Up to 5.5 V - Allows safe connection to 5 V peripherals without level-shifting circuitry. |
| Propagation Delay (tpd) | 1.0 ns to 5.7 ns @ VCC = 3.3 V - Supports >100 MHz bidirectional data transfer on properly terminated buses. |
| Bus-Hold Current (IBHL/IIBHH) | ±10 μA to ±75 μA - Actively maintains last valid logic state on un-driven data lines, preventing metastability. |
| IOFF Leakage Current | ±10 μA max @ VCC = 0 V - Limits backflow current during hot-swap or partial power-down sequences. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets JEDEC JS-001/JS-002 for robust handling in manufacturing and field service. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor drives. |

|---|---|
| Integrated 30 Ω series termination | Eliminates need for 16 discrete SMT resistors, saving board space and improving signal integrity on 50 Ω trace environments. |
| Bus-hold on all data inputs | Maintains stable logic state without external pull-ups, reducing BOM count and layout complexity for unused or intermittently driven lines. |
| IOFF partial power-down protection | Prevents damaging current flow when VCC is off but I/Os remain biased, critical for hot-plug and multi-rail systems. |
| Schmitt-trigger inputs | Accepts slow-rising/falling signals (Δt/ΔV down to 20 ns/V) without oscillation, compatible with RC-filtered or long-trace interfaces. |
| 5.5 V tolerant I/O | Directly interfaces with legacy 5 V TTL/CMOS devices while powered from 1.2–3.6 V rails, simplifying voltage translation design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit bidirectional transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC162245ADGGR | No bus-hold; IOFF supported; identical pinout and 30 Ω termination. | Lacks automatic input state retention; requires external pull-ups on unused lines. | Select when bus-hold is unnecessary and cost minimization is prioritized. |
| 74ALVC162245PW,118 | Wider VCC range (1.65–3.6 V); no bus-hold; higher drive strength (24 mA vs 12 mA). | Higher power consumption; unsuitable for 1.2 V operation; no IOFF protection. | Select for legacy ALVC compatibility or higher-current drive needs where partial power-down is not required. |
Compared with SN74LVC162245ADGGR, the 74LVCH162245ADGG,1 adds bus-hold to reduce system-level component count; compared with 74ALVC162245PW,118, it supports lower-voltage operation and includes IOFF for safer multi-rail sequencing - both trade-offs directly impact BOM cost and functional safety compliance.

FAQ
Does 74LVCH162245ADGG,1 support true 5 V operation?
No - the device requires VCC between 1.2 V and 3.6 V, but its inputs and outputs tolerate up to 5.5 V regardless of supply voltage. This allows direct connection to 5 V signal sources while powered from 3.3 V or lower, eliminating external level shifters in mixed-voltage systems.
How does bus-hold function interact with direction control?
Bus-hold is active only on data I/O pins (1A0–1A7, 2A0–2A7, 1B0–1B7, 2B0–2B7) and remains functional regardless of DIR or OE state. It holds the last valid logic level when the pin is floating, independent of data flow direction or 3-state enable status.
What is the maximum data rate supported by the integrated 30 Ω resistors?
The 30 Ω series termination supports clean signal edges up to 100 MHz on typical 50 Ω PCB traces. Measured propagation delay of 1.0–5.7 ns and rise/fall time specs confirm reliable operation in DDR2/DDR3 address/control bus applications and parallel flash interfaces.
Can 1OE and 2OE be tied together for unified 16-bit control?
Yes - tying 1OE and 2OE simplifies control logic for full 16-bit operation, but disables independent 8-bit gating. When tied, both byte lanes enter 3-state simultaneously; separate control preserves flexibility for interleaved memory access or partial bus isolation in complex systems.
