Product details
Overview
74LVCH162245ADGG,5 from Nexperia is a 16-bit CMOS bus transceiver with integrated 30 Ω series termination resistors, dual 8-bit direction control (1DIR/2DIR), dual 3-state enable (1OE/2OE), and 5 V tolerant I/O operating from 1.2 V to 3.6 V supply. It functions as two independent 8-bit transceivers or one unified 16-bit bidirectional data path in mixed-voltage systems, supporting level translation between 3.3 V and 5 V logic domains in industrial backplanes and memory expansion interfaces.
For engineers reviewing the 74LVCH162245ADGG,5 datasheet, 74LVCH162245ADGG,5 pinout, 74LVCH162245ADGG,5 application, or 74LVCH162245ADGG,5 equivalent, this device delivers verified bus hold on all data inputs, IOFF partial power-down protection, Schmitt-trigger inputs for noise immunity, and JEDEC-compliant operation across –40 °C to +125 °C - critical for robust embedded bus interface design.
Technical Context
This transceiver implements dual independent flow-through architecture: each 8-bit port (Port A and Port B) features dedicated direction (nDIR) and output enable (nOE) controls, enabling asymmetric bidirectional data routing without contention. The integrated 30 Ω series termination resistors are placed on all 16 I/O lines, reducing signal reflections on high-speed PCB traces without external components.
Bus hold circuitry is active only on data input pins (1A0–1A7, 2A0–2A7, 1B0–1B7, 2B0–2B7), eliminating need for external pull-ups on unused inputs; control pins (1DIR, 2DIR, 1OE, 2OE) lack bus hold. IOFF functionality disables outputs and blocks backflow current during partial power-down, meeting JESD78 Class II latch-up immunity requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.2 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic families |
| I/O Voltage Tolerance | Up to 5.5 V - allows safe connection to 5 V signals without level shifters in mixed-voltage systems |
| Propagation Delay (tpd) | 1.0 ns (min) to 8.5 ns (max) at VCC = 3.3 V - supports >100 MHz data rates in point-to-point bus applications |
| Integrated Termination | 30 Ω series resistor per I/O - reduces PCB component count and layout complexity for impedance-matched trace routing |
| Bus Hold Current | ±10 μA to ±500 μA (IBHL/IBHH/IBHLO/IBHHO) - actively maintains valid logic state on floating data inputs without external bias |
| IOFF Leakage | ±10 μA max at VCC = 0 V - prevents damaging back-current when powered down while system buses remain live |
| Operating Temperature | –40 °C to +125 °C - qualified for extended-temperature industrial and automotive under-hood auxiliary modules |
Pinout & Package
TSSOP48 (SOT362-1) package: plastic thin shrink small outline, 48 leads, 6.1 mm body width, 0.5 mm lead pitch, exposed pad not present. Pin 1 index marked by notch; pin 1 located at top-left corner when notch faces up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR, 2DIR | Direction control input | Active-HIGH logic selects data flow direction per 8-bit port (A→B or B→A) |
| 1OE, 2OE | Output enable input | Active-LOW logic places corresponding 8-bit port outputs into high-impedance state |
| 1A0–1A7, 2A0–2A7 | Data I/O (Port A) | Bus hold enabled; bidirectional data path for first/second 8-bit segment |
| 1B0–1B7, 2B0–2B7 | Data I/O (Port B) | Bus hold enabled; complementary bidirectional data path to Port A |
| VCC (Pins 7, 18, 31, 42) | Power supply | Four distributed supply pins minimize IR drop and improve noise immunity |
| GND (Pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight ground pins reduce ground bounce and support low-inductance return paths |
Key Features
| Feature | Design Value |
|---|---|
| Dual 8-bit flow-through architecture | Independent DIR/OE control per port enables asymmetric data routing and eliminates bus contention risk |
| Integrated 30 Ω series termination | Eliminates need for 16 discrete SMT resistors, saving PCB area and assembly cost in high-density layouts |
| Bus hold on all data inputs | Maintains stable logic state on unconnected or unterminated data lines without external pull-up/pull-down networks |
| IOFF partial power-down protection | Prevents destructive back-current flow when VCC is off but I/O buses remain at 3.3 V or 5 V |
| Schmitt-trigger inputs | Provides >0.3 V hysteresis on all control and data inputs, rejecting slow-rising/falling noise on long traces |
Applications
| Industrial Backplane Interface | Memory Expansion Subsystem |

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 |
|---|---|---|---|
| SN74LVC162245ADGGR | No bus hold; IOFF supported; identical pinout and 30 Ω termination | Lacks automatic input state retention - requires external pull resistors on unused lines | Select when bus hold is unnecessary and lowest static power is prioritized |
| 74AVCH162245DGGR | Wider VCC range (1.2 V–3.6 V), faster tpd (0.8 ns typ), no bus hold | Higher speed but no input state retention; higher drive strength increases crosstalk risk on dense boards | Select for timing-critical applications where propagation delay < 3 ns is mandatory and board layout allows careful termination |
Compared with SN74LVC162245ADGGR and 74AVCH162245DGGR, the 74LVCH162245ADGG,5 uniquely combines bus hold, 5.5 V tolerance, and industrial temperature range in a single TSSOP48 package - simplifying design for unattended systems where input floating cannot be guaranteed.

FAQ
Does the 74LVCH162245ADGG,5 support hot-plug operation?
Yes - its IOFF circuitry actively disables outputs and blocks backflow current when VCC is 0 V, allowing safe insertion/removal while 5 V or 3.3 V buses remain powered. This meets JEDEC JESD78 Class II latch-up immunity requirements and prevents damage during live system reconfiguration.
Can 1DIR and 2DIR be tied together for unified 16-bit operation?
Yes - connecting 1DIR and 2DIR enables simultaneous direction control across both 8-bit ports, converting the device into a single 16-bit transceiver. However, doing so forfeits independent port control; separate direction signals are required to operate ports asynchronously.
What is the maximum capacitive load the 74LVCH162245ADGG,5 can drive reliably?
Per datasheet Table 9, it drives up to 50 pF load capacitance at VCC = 3.0–3.6 V with ≤2.5 ns rise/fall times. Driving >50 pF may exceed specified tpd and tdis limits; for heavier loads, use external series resistors or buffer stages to maintain timing margins.
How does bus hold behave when an input exceeds VCC?
Bus hold automatically disables when VI > VCC, permitting safe 5.5 V input application without damage. During 5 V tolerant operation, the input functions as a standard CMOS gate with VIH/VIL thresholds referenced to VCC, and bus hold remains inactive until voltage drops below VCC.
