Product details
Overview
74ALVCH32245BFG8 from Renesas Electronics (formerly IDT) is a 3.3V CMOS 32-bit bus transceiver with 3-state outputs and integrated bus-hold circuitry, designed for asynchronous bidirectional data transfer between two 32-bit buses. It supports industrial temperature range (–40°C to +85°C), delivers ±24mA output drive, and features rail-to-rail swing and <500ps output skew at 3.3V.
For engineers reviewing the 74ALVCH32245BFG8 datasheet, 74ALVCH32245BFG8 pinout, 74ALVCH32245BFG8 application, or 74ALVCH32245BFG8 equivalent, key selection criteria include bus-hold functionality, 96-ball LFBGA package compatibility, 3.3V/2.5V dual-supply operation, and high-speed timing (tPLH/tPHL ≤ 3ns at VCC = 3.3V).
Technical Context
The 74ALVCH32245BFG8 implements four independent 8-bit transceiver sections, each controlled by dedicated DIR and OE pins, enabling flexible partitioning of the 32-bit bus. Its bus-hold inputs retain last logic state during high-impedance conditions, eliminating external pull resistors.
It uses 0.5µm CMOS technology with hysteresis on all inputs for noise immunity, operates across VCC = 2.5V ±0.2V or 3.3V ±0.3V, and meets MIL-STD-883 ESD ratings (>2000V HBM, >200V MM). Output drivers support heavy capacitive loads while maintaining sub-5ns propagation delay.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.5V ±0.2V or 3.3V ±0.3V - supports mixed-voltage system interfacing and legacy 2.5V logic compatibility |
| Output Drive | ±24mA - enables direct driving of moderate-to-heavy capacitive loads without external buffers |
| Propagation Delay | tPLH/tPHL ≤ 3ns @ VCC = 3.3V - ensures timing closure in high-speed 32-bit parallel interfaces |
| Output Skew | tSK(o) ≤ 500ps - guarantees simultaneous switching across all 32 bits for clean bus transitions |
| Bus-Hold Current | IBHH/IBHL = ±75µA @ VCC = 3V - maintains stable input state with minimal power overhead |
| Input Hysteresis | VH = 100mV @ VCC = 3.3V - improves noise margin against ground bounce and crosstalk |
| ESD Rating | >2000V HBM, >200V MM - provides robust handling during board assembly and field operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ALVCH32245KR | TI variant in 96-pin LFBGA; identical electrical specs but different thermal pad configuration and JEDEC marking | Same functional behavior and pinout; validated for TI-specific reference designs only | Select when sourcing from TI-authorized channels or aligning with TI-designated BOMs |
| 74LVC32245ABQ | Nexperia version in 96-ball HVQFN; lacks bus-hold; lower drive (±24mA still supported) but no hysteresis or industrial temp guarantee | Suitable for commercial-temp consumer electronics; requires external pull resistors on A-side inputs | Choose only for cost-sensitive, non-industrial applications where bus-hold is not required |
Compared with SN74ALVCH32245KR and 74LVC32245ABQ, the 74ALVCH32245BFG8 uniquely combines bus-hold, industrial temperature rating, and guaranteed hysteresis - making it the sole option for unbuffered, hot-swap-capable 32-bit bus interfaces in harsh environments.

FAQ
What is the operating temperature range for the 74ALVCH32245BFG8?
The 74ALVCH32245BFG8 is rated for industrial temperature operation from –40°C to +85°C. This specification is fully tested and guaranteed per the datasheet's DC and AC electrical characteristics tables, ensuring reliable performance in factory automation, outdoor infrastructure, and other thermally demanding environments where standard commercial-grade logic would fail.
Does the 74ALVCH32245BFG8 support both 2.5V and 3.3V supply voltages?
Yes, the 74ALVCH32245BFG8 supports dual supply operation: 2.5V ±0.2V and 3.3V ±0.3V. The device maintains full functionality-including ±24mA drive strength, sub-5ns timing, and bus-hold-across both ranges. This allows seamless integration between legacy 2.5V subsystems and modern 3.3V logic domains without level-shifting components.
How does bus-hold functionality work on the 74ALVCH32245BFG8?
The 74ALVCH32245BFG8 implements bus-hold on all Side A (xAx) inputs, using internal feedback circuitry to retain the last valid logic state when the input goes high-impedance. With IBHH/IBHL = ±75µA at VCC = 3V, it actively clamps floating nodes without external resistors-reducing BOM cost, PCB space, and risk of metastability during hot-swap or power sequencing events involving the 74ALVCH32245BFG8.
What is the maximum output skew specified for the 74ALVCH32245BFG8?
The 74ALVCH32245BFG8 specifies maximum output skew tSK(o) ≤ 500ps across any two outputs switching in the same direction under VCC = 3.3V conditions. This tight skew ensures synchronized transitions across all 32 data lines, which is essential for setup/hold timing compliance in high-speed parallel interfaces such as those used in the 74ALVCH32245BFG8's target applications.
Is the 74ALVCH32245BFG8 pin-compatible with other ALVCH32245 variants?
The 74ALVCH32245BFG8 uses the standard 96-ball LFBGA footprint defined in the IDT datasheet, and its pin functions (1DIR–4DIR, 1OE–4OE, xAx/xBx, VCC/GND) match the industry-standard ALVCH32245 family layout. However, mechanical differences-such as thermal pad design or ball metallurgy-may exist between manufacturers; always verify land pattern and solder mask requirements before PCB layout for the 74ALVCH32245BFG8.
