Nexperia USA Inc. 74AVC1T8832GSX

Overview

74AVC1T8832 from Nexperia is a single dual-supply translating 2-input OR gate with independent strobe inputs (STRA, STRB), supporting voltage translation between 0.8 V and 3.6 V on both VCC(A) and VCC(B). It implements Y = STRA·A + STRB·B, features IOFF partial power-down protection, and operates across -40 °C to +125 °C for industrial interface bridging in mixed-voltage SoC subsystems.

For engineers reviewing the 74AVC1T8832 datasheet, 74AVC1T8832 pinout, 74AVC1T8832 application, or 74AVC1T8832 equivalent, key selection criteria include dual-supply rail independence, Suspend-mode high-impedance output behavior, JEDEC-compliant voltage level translation, and guaranteed 500 Mbit/s data rate at 1.8 V–3.3 V translation.

Technical Context

This device implements a dual-rail logic OR function with separate enable control per input path: STRA gates A to Y, STRB gates B to Y. Both input domain (VCC(A)) and output domain (VCC(B)) are independently configurable from 0.8 V to 3.6 V, enabling bidirectional voltage translation without external level shifters.

The IOFF circuit enforces high-impedance output when either VCC(A) or VCC(B) is at GND, preventing backflow current during partial power-down. Input thresholds scale with VCC(A); output drive strength and VOL/VOH are referenced strictly to VCC(B), ensuring predictable interfacing with downstream 1.2 V, 1.8 V, or 3.3 V receivers.

FAQ

What happens to the Y output when VCC(A) = 0 V but VCC(B) = 3.3 V?

When VCC(A) is at GND while VCC(B) remains powered, the device enters Suspend mode: Y transitions to a high-impedance OFF-state (Z), regardless of input states. This IOFF behavior prevents back-driving or leakage into the unpowered A-side circuitry, satisfying JEDEC JESD78 Class II latch-up immunity requirements.

Can STRA and STRB be tied together and driven by a single control signal?

Yes - STRA and STRB may be shorted and driven by one signal to implement a conventional 2-input OR with global enable. The logic equation simplifies to Y = STRA·(A + B), preserving full voltage translation capability. Input loading remains within datasheet limits (II ≤ ±1 μA) due to CMOS input structure.

Is the 500 Mbit/s data rate guaranteed across the full -40 °C to +125 °C range?

No - the 500 Mbit/s rating applies only at Tamb = 25 °C with VCC(A) = VCC(B) = 1.8 V or 3.3 V. Over temperature, maximum usable rate decreases: at +125 °C and VCC(A)=VCC(B)=3.3 V, tpd max = 3.9 ns (≈256 Mbit/s), per Table 12. System-level timing margins must account for worst-case propagation delay.

Does the device support hot insertion when VCC(B) is powered before VCC(A)?

Yes - the IOFF circuit activates whenever either supply is at GND, including during asymmetric power sequencing. If VCC(B) ramps first, Y remains in high-Z until VCC(A) reaches valid operating voltage (>0.8 V), preventing undefined output states or bus contention during power-up.
