Nexperia USA Inc. 74LVC827ADB,118

Overview

74LVC827ADB,118 from Nexperia is a 10-bit non-inverting buffer/line driver with dual 3-state enable inputs (OE1, OE2), 5 V tolerant I/O, 1.2 V to 3.6 V supply operation, and −40 °C to +125 °C temperature range. It functions as a level-translating bus interface in mixed-voltage systems such as industrial control backplanes and FPGA I/O expansion.

For engineers reviewing the 74LVC827ADB,118 datasheet, 74LVC827ADB,118 pinout, 74LVC827ADB,118 application, or 74LVC827ADB,118 equivalent, key selection criteria include 5 V tolerance on all I/O pins, dual independent output enables, propagation delay ≤6.7 ns at 3.3 V, 3-state leakage <0.1 µA, and SSOP24 package compatibility with high-density PCB layouts.

Technical Context

This device implements ten independent buffer channels, each with non-inverting logic and bidirectional 5 V tolerant I/O-enabling safe interfacing between 3.3 V LVC logic and legacy 5 V TTL or CMOS buses. The dual active-low OE inputs (pins 1 and 13) allow partitioned bus control: OE1 governs Y0–Y4, OE2 governs Y5–Y9 per functional diagram and pin description.

Its static characteristics support VIH = 2.0 V (min) and VIL = 0.8 V (max) at VCC = 3.0–3.6 V, while dynamic performance delivers tpd = 1.0–6.7 ns and output skew tsk(o) ≤1.5 ns across temperature. The device complies with JEDEC JESD8-7A, JESD8-5A, and JESD8-C/JESD36 for multi-voltage interoperability.

FAQ

Can 74LVC827ADB,118 operate with VCC = 1.2 V while driving 5 V signals?

Yes. The device is fully specified down to VCC = 1.2 V and maintains 5 V tolerance on all I/O pins across the entire supply range. Input thresholds scale with VCC (e.g., VIH = 1.08 V min at 1.2 V), and output drive remains functional-enabling ultra-low-power operation in battery-backed systems without sacrificing 5 V bus compatibility.

What is the maximum capacitive load supported per output at 3.3 V supply?

Each output supports up to 50 pF load capacitance at VCC = 3.0–3.6 V while meeting tpd ≤6.7 ns and VOL ≤0.55 V at IO = 24 mA. This is verified in Table 9 test conditions using 50 pF CL and 500 Ω RL, confirming reliable operation into typical PCB trace and IC input capacitance in high-speed digital interfaces.

How does dual OE control improve system-level bus management?

OE1 (pin 1) controls Y0–Y4 and OE2 (pin 13) controls Y5–Y9, enabling independent gating of two 5-bit bus segments. This allows time-multiplexed sharing of a single 10-bit physical bus between CPU data and peripheral address paths-or selective isolation during fault conditions without disabling the entire interface.

Is 74LVC827ADB,118 pin-compatible with older 74-series buffers like 74LS244?

No. While functionally similar as a 10-bit buffer, 74LVC827ADB,118 uses a different pinout: inputs A0–A9 occupy pins 2–11, outputs Y0–Y9 occupy pins 14–23, and dual OE inputs are on pins 1 and 13. The 74LS244 has separate input/output groups and single OE-requiring PCB redesign and logic inversion for drop-in replacement.
