Nexperia USA Inc. 74LVC827AD,118

Overview

74LVC827AD from Nexperia is a 10-bit non-inverting buffer/line driver with dual 3-state enable inputs (OE1, OE2), 5 V tolerant I/O, and operation from 1.2 V to 3.6 V supply. It supports mixed-voltage translation between 3.3 V and 5 V logic domains, delivers ±24 mA output drive at 3.0 V, and operates across −40 °C to +125 °C for industrial control backplanes and FPGA I/O expansion.

For engineers reviewing the 74LVC827AD datasheet, 74LVC827AD pinout, 74LVC827AD application, or 74LVC827AD equivalent, key selection criteria include 5 V tolerance on all I/O pins, dual independent 3-state control, propagation delay ≤6.7 ns at 3.3 V, low ICC (≤40 µA) over full temperature range, and SO24 package compatibility with legacy PCB footprints.

Technical Context

This device implements ten independent buffer channels with active-low enable logic per group: OE1 controls Y0–Y4 and OE2 controls Y5–Y9. Each output enters high-impedance state when its respective OE is HIGH, enabling bus sharing and signal isolation in multi-drop systems.

Input thresholds comply with JEDEC JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V), ensuring reliable switching across LVC voltage ranges. The 5.5 V absolute max input/output rating allows safe interfacing with 5 V peripherals while powered from 1.65 V–3.6 V supplies.

FAQ

Can 74LVC827AD operate with VCC = 1.2 V while accepting 5 V inputs?

Yes. The device is fully specified down to 1.2 V VCC and maintains 5 V tolerance on all inputs and outputs per Table 4 (VI and VO limits: −0.5 V to +6.5 V). Input leakage remains ≤±20 µA at VI = 5.5 V and VCC = 1.2 V, ensuring safe operation without clamping diode conduction.

What is the maximum capacitive load this device can drive while maintaining timing specs?

Per Figure 6 test conditions and Table 9, the device is characterized up to 50 pF load capacitance at VCC ≥2.7 V. At 3.3 V and 50 pF, tpd remains ≤6.7 ns and tdis ≤8.5 ns. Driving >50 pF increases propagation delay nonlinearly and may violate setup/hold margins in high-speed interfaces.

How does dual OE control improve system-level reliability?

Dual OE inputs (OE1 for Y0–Y4, OE2 for Y5–Y9) allow independent disabling of bus segments. This prevents contention during partial reconfiguration (e.g., FPGA partial bitstream updates) and enables fault containment-if one subsystem fails, only its associated 5-bit segment is isolated while the rest remains operational.

Is 74LVC827AD qualified for automotive applications?

No. Although rated for −40 °C to +125 °C, the device is not AEC-Q100 qualified and lacks automotive-specific qualification testing (e.g., HTOL, ESD per ISO 10605). Nexperia explicitly states non-automotive qualification in Section 15.3; use requires customer-led validation for safety-critical functions.
