Product details
Overview
74LVCH32245ABFG8 from Renesas Electronics is a 3.3V CMOS 32-bit bus transceiver with 3-state outputs, 5V-tolerant I/O, bus-hold functionality, ±24mA balanced drivers, and industrial temperature range (–40°C to +85°C). It operates as four independent 8-bit or one unified 32-bit transceiver in mixed-voltage data buses.
For engineers reviewing the 74LVCH32245ABFG8 datasheet, 74LVCH32245ABFG8 pinout, 74LVCH32245ABFG8 application, or 74LVCH32245ABFG8 equivalent, key selection criteria include 5V/3.3V level translation capability, output skew <500ps, bus-hold input retention, hot-insertion support, and LFBGA-96 package compatibility for high-density PCB layouts.
Technical Context
This device implements asynchronous bidirectional data transfer between two 32-bit busses (A and B) using dedicated DIR and OE controls per 8-bit segment. Direction is set by DIR inputs; OE inputs override direction and force high-impedance on both ports. All I/O pins feature hysteresis and bus-hold to prevent floating states without external resistors.
The transceiver uses dual-metal CMOS process for low static power (0.4μW typ.) and supports extended VCC range (2.7V–3.6V). Its ±24mA drive strength maintains signal integrity under moderate loads, while tPLH/tPHL propagation delays are specified down to 1ns (typ.) at 3.3V, enabling use in high-speed digital interconnects.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.7V to 3.6V - ensures operation across wide supply tolerance and brown-out resilience in industrial systems |
| IO Drive Strength | ±24mA - enables direct driving of stub-loaded transmission lines or multiple CMOS inputs without buffers |
| Output Skew (tSK(o)) | ≤500ps - guarantees tight timing alignment across all 32 outputs for synchronous bus capture |
| I/O Voltage Tolerance | 0V to 6.5V - allows safe interfacing with 5V logic while powered from 3.3V, eliminating level-shifters |
| Bus-Hold Current | ±75µA (typ.) - actively retains last valid logic state on un-driven inputs, removing need for pull-up/down resistors |
| Propagation Delay | 1.0–4.0ns (typ. at 3.3V) - supports >200MHz bus toggle rates in point-to-point or lightly loaded configurations |
| Operating Temp | –40°C to +85°C - qualified for deployment in industrial control, telecom infrastructure, and factory automation |
Pinout & Package
74LVCH32245ABFG8 is housed in a 96-ball Low-Profile Fine-Pitch Ball Grid Array (LFBGA) package, footprint code BFG96, with 0.8mm ball pitch and 13mm × 13mm body size. The package supports automated assembly and thermal dissipation suitable for dense logic interfaces.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1DIR–4DIR | Direction Control Input (Active HIGH) | Selects data flow direction per 8-bit segment: LOW = B→A, HIGH = A→B |
| 1OE–4OE | Output Enable Input (Active LOW) | Disables both A/B ports to high-Z when HIGH; overrides DIR when asserted |
| 1A1–4A8, 1B1–4B8 | Bidirectional I/O Port Pins | 32-bit A-side and 32-bit B-side data paths; all 5V tolerant with bus-hold on A/B inputs |
| VCC / GND | Power Supply / Ground | Multiple VCC/GND balls distributed for low-impedance decoupling and reduced switching noise |
Key Features
| Feature | Design Value |
|---|---|
| 5V-tolerant I/O | Enables seamless integration into mixed-supply systems without external voltage translators |
| Bus-hold circuitry | Eliminates external pull resistors on unused or intermittently driven inputs, reducing BOM count and layout area |
| Hot-insertion support | Allows safe board insertion/removal under power via controlled I/O clamp behavior and power-off leakage limits |
| Balanced ±24mA drivers | Provides symmetrical rise/fall times and consistent edge rates across all 32 outputs for EMI reduction |
| Low static power | 0.4μW typical ICC - extends uptime in always-on industrial gateways and remote I/O modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |

FAQ
What is the operating voltage range for the 74LVCH32245ABFG8?
The 74LVCH32245ABFG8 operates across a VCC range of 2.7V to 3.6V, with nominal performance specified at 3.3V ±0.3V. This extended range ensures reliable function during supply fluctuations common in industrial power rails and enables compatibility with both standard and low-dropout regulators without derating.
Does the 74LVCH32245ABFG8 support hot insertion?
Yes, the 74LVCH32245ABFG8 supports hot insertion due to its 5V-tolerant I/O structure, controlled clamp diode behavior (VIK ≤ –1.2V), and low power-off leakage (±50µA). These features prevent latch-up and excessive current draw when inserted into a live backplane, making it suitable for modular industrial and telecom systems requiring field-replaceable units.
How does bus-hold functionality work on the 74LVCH32245ABFG8?
The 74LVCH32245ABFG8 implements bus-hold on all A- and B-side I/O pins, using internal feedback circuits that sustain the last valid logic state with ±75µA typical hold current. This eliminates floating inputs during tri-state transitions or unconnected traces, removing the need for external pull-up or pull-down resistors and reducing PCB complexity and cost.
What is the maximum output skew specification for the 74LVCH32245ABFG8?
The 74LVCH32245ABFG8 specifies a maximum output skew (tSK(o)) of 500ps across any two outputs switching in the same direction within the same package. This tight skew enables precise timing alignment in high-speed parallel bus applications such as memory expansion and FPGA-to-ASIC interconnects where simultaneous data capture is critical.
Is the 74LVCH32245ABFG8 pin-compatible with other LFBGA-96 bus transceivers?
The 74LVCH32245ABFG8 shares the same 96-ball LFBGA (BFG96) mechanical footprint and pinout with Renesas' 74ALVCH32245ABFG8 and 74LVCH32244ABFG8 variants. However, functional compatibility requires verification of DIR/OE logic polarity, bus-hold presence, and drive strength-since the 74LVCH32245ABFG8 is not pin-compatible with non-Renesas LFBGA-96 transceivers due to differing internal architecture and signal mapping.
