Product details

Overview

74AXP4T245BQX from Nexperia is a 4-bit dual-supply translating transceiver with 3-state outputs, enabling bidirectional level translation between independent voltage domains (0.9 V to 5.5 V). It supports two 2-bit or one 4-bit configuration, features separate VCC(A) and VCC(B) supplies, direction control (nDIR), output enable (nOE), and IOFF partial power-down protection. Used in mixed-voltage SoC interconnects, FPGA I/O bridging, and industrial controller bus isolation.

For engineers reviewing the 74AXP4T245BQX datasheet, 74AXP4T245BQX pinout, 74AXP4T245BQX application, or 74AXP4T245BQX equivalent, key selection criteria include dual-rail voltage flexibility (0.9–5.5 V per rail), guaranteed glitch-free operation during supply transitions (20 mV/µs to 5.5 V/s), IOFF-enabled suspend mode, and −40 °C to +125 °C operation for automotive and industrial environments.

Technical Context

The device implements patented circuitry that prevents output glitches during asynchronous power-up/down of VCC(A) and VCC(B), ensuring robustness in systems with non-sequenced supplies. Its dual-reference architecture isolates nAn/nDIR/nOE to VCC(A) and nBn to VCC(B), enabling true bidirectional translation without external biasing.

Functionally, it operates as two independent 2-bit transceivers (1A1/1B1/1A2/1B2 and 2A1/2B1/2A2/2B2), each controlled by dedicated nDIR/nOE pins. The IOFF circuit disables outputs and blocks backflow current when either supply is at GND, supporting hot-swap and partial power-down compliance.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC(A) / VCC(B) Range	0.9 V to 5.5 V per rail - enables translation across 0.9 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic domains
Propagation Delay (nAn→nBn)	Min 2.7 ns / Max 15 ns at VCC = 5.0 V - supports high-speed interface bridging up to ~70 MHz data rate
IOFF Leakage Current	±0.1 μA max at 25 °C - ensures safe bus isolation during power-down without damaging backflow
Input Capacitance (CI)	1.2 pF typical - minimizes signal loading on driving sources, critical for high-frequency integrity
Operating Temperature	−40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and harsh-environment embedded use

Power Dissipation Cap. (CPD)	10.9 pF max at 5.0 V - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N)

Pinout & Package

DHVQFN16 package (SOT763-1), 2.5 × 3.5 × 0.85 mm body, no leads, thermal-enhanced, exposed die pad (non-electrical, optional GND connection).

Pin/Terminal	Circuit Role	Design Meaning
1	VCC(A)	Supply for A-side ports (nAn, nDIR, nOE); defines reference for all A-side logic thresholds
2, 3	1DIR, 2DIR	Active-HIGH direction controls for respective 2-bit channels; HIGH = A→B, LOW = B→A
4–7	1A1, 1A2, 2A1, 2A2	A-side bidirectional data terminals; referenced to VCC(A)
8, 9	GND	Common ground return for both supply domains; both pins must be connected
10–13	2B2, 2B1, 1B2, 1B1	B-side bidirectional data terminals; referenced to VCC(B)
14, 15	2OE, 1OE	Active-LOW output enables; drives associated channel into high-impedance OFF-state when HIGH
16	VCC(B)	Supply for B-side ports (nBn); defines reference for all B-side logic thresholds

Key Features

Feature	Design Value
Glitch-free supply transition	Eliminates output disturbances during VCC(A)/VCC(B) ramp rates from 20 mV/µs to 5.5 V/s - removes need for external sequencing or hold-off circuits
Independent dual-rail operation	Supports simultaneous 1.2 V ↔ 3.3 V and 1.8 V ↔ 5.0 V translations on same device - reduces component count in multi-voltage systems
IOFF partial power-down	Blocks >99.9% of backflow current when either VCC is at 0 V - enables safe hot-plug and low-power suspend modes
Low dynamic power	CPD = 10.9 pF max at 5 V - cuts switching power vs. legacy translators (e.g., 74LVC4245: CPD ≈ 25 pF)
High noise immunity	Meets JEDEC JESD8-x standards across 1.1 V–5.5 V - ensures reliable operation in electrically noisy industrial environments

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-supply translating transceiver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74AVC4T245RTER	Lower VCC min (1.2 V), higher ICC (max 40 μA), no IOFF, only −40 °C to +85 °C rating	Lacks suspend-mode isolation; unsuitable for hot-swap or automotive under-hood use	Select when cost sensitivity outweighs extended temp/IOFF needs and system uses ≥1.2 V rails only
74LVC4245APW	Single-supply (3.3 V only), no dual-rail translation, higher CPD (25 pF), no glitch suppression	Requires external level-shifting for mixed-voltage interfaces; adds design complexity and timing uncertainty	Choose only for legacy 3.3 V-only systems where dual-rail capability is unnecessary

Compared with SN74AVC4T245RTER and 74LVC4245APW, the 74AXP4T245BQX uniquely delivers full 0.9–5.5 V dual-rail support, guaranteed glitch-free supply transitions, and IOFF-enabled suspend mode - making it the sole option qualified for automotive AEC-Q100 Grade 1 and industrial −40 °C to +125 °C applications requiring robust mixed-voltage interoperability.

FAQ

Can 74AXP4T245BQX translate between 0.9 V and 5.0 V simultaneously?

Yes. VCC(A) can be set to 0.9 V (for 0.9 V logic domain) and VCC(B) to 5.0 V (for 5.0 V domain), with inputs referenced to their respective supplies. The device guarantees correct logic thresholds, propagation delay (tpd ≤32 ns), and output drive (VOH/VOL) across this full range per JEDEC-compliant specifications.

What happens when only VCC(A) is powered and VCC(B) = 0 V?

In this suspend mode, both A-side and B-side I/O pins enter high-impedance OFF-state due to internal IOFF circuitry. Output leakage is limited to ±0.1 μA max, preventing backflow current and protecting downstream 5.0 V circuitry - a critical feature for hot-plug and modular system designs.

Is the DHVQFN16 package thermally enhanced?

Yes. The SOT763-1 package features an exposed thermal pad (pin 1 index area) that improves thermal resistance. Though electrically isolated, connecting this pad to PCB ground via thermal vias reduces junction-to-board θJB by up to 30%, supporting continuous operation at full rated current across −40 °C to +125 °C.

Does 74AXP4T245BQX require power supply sequencing?

No. Patented circuitry eliminates the need for VCC(A) and VCC(B) sequencing - either supply may power up/down first or independently. Glitch-free operation is guaranteed for ramp rates from 20 mV/µs to 5.5 V/s, simplifying power architecture and eliminating sequencing ICs or RC delays.
