Product details
Overview
74LVCH32245AEC/G:5 from NXP Semiconductors is a 32-bit non-inverting 3-state bus transceiver with four independent direction (nDIR) and output enable (nOE) controls, operating from 2.3 V to 3.6 V supply, tolerant to 5.5 V on I/O pins, and specified for −40 °C to +125 °C. It enables bidirectional data flow between mixed-voltage domains (e.g., 3.3 V logic interfacing with 5 V peripherals) in high-density PCB layouts.
For engineers reviewing the 74LVCH32245AEC/G:5 datasheet, 74LVCH32245AEC/G:5 pinout, 74LVCH32245AEC/G:5 application, or 74LVCH32245AEC/G:5 equivalent, key selection criteria include 5 V tolerance on all I/Os, bus hold on all data inputs eliminating external pull-ups, LFBGA96 package compatibility with fine-pitch routing, and guaranteed 3-state isolation during power sequencing.
Technical Context
This device implements four independent 8-bit transceiver sections (1A/1B through 4A/4B), each with dedicated nDIR and nOE control. Direction control determines signal flow (A→B or B→A); nOE asserts high-impedance on both sides when HIGH. Bus hold circuitry actively maintains last-valid logic state on unused data inputs without external components.
It complies with JEDEC standards JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V). ESD protection exceeds 2000 V HBM, 200 V MM, and 1000 V CDM, supporting robust operation in industrial environments with variable ground potentials.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.3 V to 3.6 V - Enables direct integration into 3.3 V systems while maintaining compatibility with legacy 2.7 V rails. |
| I/O voltage tolerance | Up to 5.5 V - Allows safe connection to 5 V buses without level shifters or clamping diodes. |
| Propagation delay | 1.0 ns (min) to 6.0 ns (max) at VCC = 3.0–3.6 V - Supports high-speed data transfer in memory or peripheral interfaces up to ~160 MHz. |
| Bus hold current | ±75 μA at VCC = 3.0 V - Ensures stable input state retention without external biasing, reducing BOM count and layout area. |
| Operating temperature | −40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLC backplanes, and telecom line cards. |
| Power dissipation capacitance | 18.5 pF per buffer at VCC = 3.0–3.6 V - Enables accurate dynamic power estimation for thermal design in dense FPGA/ASIC interconnects. |
| Output drive strength | 24 mA sink/source at VCC = 3.0 V - Drives standard TTL loads and multiple CMOS inputs with controlled edge rates. |
Pinout & Package
Package: LFBGA96 (SOT536-1), plastic low-profile fine-pitch ball grid array, 13.5 × 5.5 × 1.05 mm body, 96 solder balls.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A[0:7], 1B[0:7]–4A[0:7], 4B[0:7] | Data I/O pairs per section | Eight bidirectional data lines per of four independent transceiver banks; A-side and B-side are electrically symmetric and interchangeable per section. |
| 1DIR–4DIR | Direction control input (active HIGH) | Determines data flow direction per section: DIR = LOW → A→B; DIR = HIGH → B→A; no internal pull-up/pull-down. |
| 1OE–4OE | Output enable input (active LOW) | Asserts 3-state (high-Z) on both A and B ports of corresponding section; must be pulled HIGH via resistor during power-up to prevent bus contention. |
| VCC | Supply voltage | Eight dedicated VCC balls (C3/C4/F3/F4/L3/L4/P3/P4) minimize IR drop and supply noise in high-current switching scenarios. |
| GND | Ground reference | Sixteen GND balls distributed across package perimeter reduce ground bounce and improve signal integrity for all 32 data paths. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V tolerant I/Os | Enables direct interface between 3.3 V ASIC/FPGA and 5 V legacy peripherals (e.g., EEPROMs, displays, sensors) without external level translators. |
| Integrated bus hold | Eliminates need for 32 external pull-up/pull-down resistors on data inputs, saving PCB area, BOM cost, and assembly steps in space-constrained modules. |
| MULTIBYTE flow-through pinout | Standardized A/B pairing and linear ball mapping (e.g., 1A0–1A7 adjacent, 1B0–1B7 mirrored) simplifies trace routing and reduces crosstalk in high-speed parallel buses. |
| Low-inductance power delivery | Multiple VCC/GND ball pairs distributed across package footprint suppress simultaneous switching noise (SSN), critical for clean timing in DDR or address/data multiplexed systems. |
| Wide temperature range | Guaranteed operation from −40 °C to +125 °C supports deployment in engine control units, base station RF modules, and industrial motor drives without derating. |
Applications
| Industrial PLC Backplane Interface | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3245APM | Same 32-bit architecture and 5 V tolerance, but uses TSSOP-56 package (14 × 6.2 mm) with gull-wing leads instead of LFBGA96; higher thermal resistance (θJA = 70 °C/W vs. 35 °C/W). | Preferred for prototyping or low-volume boards where reworkability and socket compatibility outweigh density constraints. | Select SN74LVC3245APM when manual soldering, visual inspection, or field repair is required; avoid in thermally constrained or high-reliability automotive modules. |
| 74ALVCH32245AEC | Pin-compatible variant with ALVC logic family: wider supply range (2.3–3.6 V same), but lower drive strength (12 mA vs. 24 mA at 3.0 V) and higher static current (ICC ≤ 80 μA vs. ≤ 40 μA). | Suitable for ultra-low-power battery-backed monitoring nodes where peak drive capability is secondary to quiescent current minimization. | Choose 74ALVCH32245AEC only when system-level power budget demands sub-50 μA ICC and full 24 mA drive is unnecessary; verify timing margins with reduced slew rate. |
Compared with SN74LVC3245APM and 74ALVCH32245AEC, the 74LVCH32245AEC/G:5 delivers superior thermal performance and drive strength in the smallest footprint, making it optimal for production-grade high-density interconnects where board space and power efficiency are co-constrained.

FAQ
What is the maximum allowable input voltage on data pins of the 74LVCH32245AEC/G:5?
The 74LVCH32245AEC/G:5 supports up to 5.5 V on all data input pins regardless of VCC level, enabling safe interfacing with 5 V logic families without external clamping. This rating is absolute and applies even when VCC = 0 V, provided input current remains within ±50 mA limits per the datasheet limiting values table.
How does the bus hold feature function on the 74LVCH32245AEC/G:5, and which pins support it?
The bus hold circuit is integrated on all data input pins (1A[0:7] through 4B[0:7]) of the 74LVCH32245AEC/G:5, actively maintaining the last-valid logic state without external resistors. It is disabled when VI > VCC, allowing 5.5 V inputs; control pins (nDIR/nOE) do not have bus hold. Sustaining current is ±75 μA at VCC = 3.0 V.
Can the 74LVCH32245AEC/G:5 operate reliably during power-up sequences where VCC ramps slowly?
Yes - the 74LVCH32245AEC/G:5 enters high-impedance state when VCC = 0 V and maintains 3-state outputs during power ramp. To ensure isolation before VCC stabilizes, tie all nOE pins to VCC via a pull-up resistor (minimum value determined by driver sink capability); this prevents bus contention in multi-rail systems.
What is the pin compatibility status between 74LVCH32245AEC/G:5 and other members of the LVCH family?
The 74LVCH32245AEC/G:5 shares identical pinout, functionality, and electrical characteristics with all 74LVCH32245A variants (e.g., 74LVCH32245ABQ, 74LVCH32245APW), differing only in packaging (LFBGA96 vs. TSSOP-56 vs. HVQFN-56). No PCB redesign is needed when migrating between these packages if mechanical constraints permit.
Does the 74LVCH32245AEC/G:5 meet automotive qualification standards?
No - the 74LVCH32245AEC/G:5 is specified for −40 °C to +125 °C operation but is not AEC-Q100 qualified. It lacks automotive-specific stress testing, failure analysis reporting, and PPAP documentation. For automotive use, NXP recommends the pin-compatible AEC-Q100 qualified 74LVCH32245AQEC variant.
