Product details
Overview
74LVCH16245ADGG,11 from Nexperia is a 16-bit CMOS bus transceiver with dual 8-bit directional control (1DIR/2DIR), dual 3-state output enables (1OE/2OE), 5 V-tolerant inputs, and integrated bus hold on all data I/Os. It operates from 1.2 V to 3.6 V, supports mixed-voltage translation between 3.3 V and 5 V systems, and is rated for -40 °C to +125 °C. Used in high-density PCB interconnects requiring bidirectional data flow control, such as memory expansion buses and FPGA-to-ASIC interface bridges.
For engineers reviewing the 74LVCH16245ADGG,11 datasheet, 74LVCH16245ADGG,11 pinout, 74LVCH16245ADGG,11 application, or 74LVCH16245ADGG,11 equivalent, this device delivers verified 5 V tolerance, sub-6 ns propagation delay at 3.3 V, IOFF-enabled partial power-down protection, Schmitt-trigger input noise immunity, and bus-hold functionality eliminating external pull-ups - critical for robust industrial control backplanes and automotive body electronics gateways.
Technical Context
This transceiver implements two independent 8-bit bidirectional data paths, each with dedicated direction (DIR) and output enable (OE) controls. Its dual OE architecture allows selective 3-state disabling of either 8-bit port without affecting the other, enabling flexible bus arbitration in multi-master systems.
The device integrates bus-hold circuitry on all 16 data I/O pins (A0–A7, B0–B7), sustaining logic states during floating conditions, and features IOFF circuitry that disables outputs and blocks backflow current when VCC = 0 V - essential for hot-swap and power-gating applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 1.2 V to 3.6 V - enables direct interfacing with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains |
| Input voltage tolerance | Up to 5.5 V - permits safe connection to 5 V legacy peripherals without level shifters |
| Propagation delay (tpd) | 1.0 ns (min) to 6.0 ns (max) at VCC = 3.0–3.6 V - ensures timing compliance in high-speed parallel buses |
| Bus hold current | ±60 μA to ±75 μA at VCC = 3.0 V - actively maintains valid logic levels on unused data lines |
| IOFF leakage | ±10 μA max at VCC = 0 V - prevents damaging back-current during system power sequencing |
| Operating temperature | -40 °C to +125 °C - qualified for under-hood automotive and industrial motor drive environments |

| 1OE, 2OE | Output enable input | Active-LOW control enabling/disabling 3-state output drivers for respective 8-bit ports |
| 1A0–1A7, 2A0–2A7 | Data I/O port A | First and second 8-bit bidirectional data terminals connected to local subsystem (e.g., microcontroller side) |
| 1B0–1B7, 2B0–2B7 | Data I/O port B | First and second 8-bit bidirectional data terminals connected to remote subsystem (e.g., memory or peripheral side) |
| VCC (pins 7, 18, 31, 42) | Power supply | Four distributed supply pins minimize IR drop and improve noise immunity across wide operating range |
| GND (pins 4, 10, 15, 21, 28, 34, 39, 45) | Ground reference | Eight ground pins reduce ground bounce and support low-inductance return paths for fast switching |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent 8-bit control | Separate DIR/OE per port enables asymmetric bus arbitration and partial port isolation |
| Integrated bus hold | Eliminates need for 16 external pull-up resistors on data lines - reduces BOM count and layout area |
| IOFF partial power-down | Prevents back-current flow when VCC is off - required for PCIe-style hot-plug and power-rail sequencing |
| Schmitt-trigger inputs | Provides >0.3 V hysteresis - tolerates slow-rising signals from mechanical switches or long traces |
| 5 V tolerant inputs | Accepts 0–5.5 V input voltages while powered from 1.2–3.6 V - enables seamless 3.3 V ↔ 5 V voltage translation |

FAQ
Does 74LVCH16245ADGG,11 support hot-swap operation?
Yes. Its IOFF circuitry actively disables outputs and blocks backflow current when VCC = 0 V, preventing damage during live insertion/removal in backplane or modular systems. This feature is validated per JEDEC JESD78 and confirmed in the datasheet's limiting values table (IOFF ≤ ±20 μA at VCC = 0 V).
Can 74LVCH16245ADGG,11 interface directly with 5 V TTL devices?
Yes. All inputs tolerate up to 5.5 V regardless of VCC level (1.2–3.6 V), allowing direct connection to 5 V TTL outputs without external level shifters. Output HIGH voltage (VOH ≥ 2.2 V at 24 mA load, VCC = 3.0 V) meets TTL input HIGH threshold requirements.
What is the function of the bus hold circuit?
The bus hold circuit maintains the last-valid logic state on each data I/O (A0–A7, B0–B7) when the line floats, drawing ±60–75 μA to sustain VIH/VIL. It eliminates external pull-up/pull-down resistors and prevents metastability in unconnected or intermittently driven bus segments.
How does the dual OE architecture improve system design?
Dual OE (1OE/2OE) allows independent 3-state control of each 8-bit port, enabling time-multiplexed bus sharing, fault isolation, and dynamic reconfiguration - e.g., holding one port in high-Z while driving the other, critical for multi-master arbitration in industrial networks.
