Nexperia USA Inc. 74LVC827APW,112

Overview

74LVC827APW,112 from Nexperia is a 10-bit non-inverting buffer/line driver with dual 3-state enable (OE1, OE2) and 5 V tolerant I/O, operating from 1.2 V to 3.6 V supply. It supports mixed-voltage translation between 3.3 V and 5 V logic domains, delivers ≤8.5 ns propagation delay at 3.3 V, and withstands 5.5 V on outputs in 3-state mode - used in bus interface, memory address buffering, and FPGA I/O expansion.

For engineers reviewing the 74LVC827APW,112 datasheet, 74LVC827APW,112 pinout, 74LVC827APW,112 application, or 74LVC827APW,112 equivalent, key selection criteria include 5 V tolerance on all I/O pins, dual independent output enables, guaranteed operation up to +125 °C, and TSSOP24 package compatibility with high-density PCB layouts.

Technical Context

This device implements two active-low 3-state enable inputs controlling ten buffered outputs simultaneously. Its CMOS input structure accepts TTL- and LVTTL-compatible logic levels across the full 1.2–3.6 V VCC range, while output drivers maintain rail-to-rail swing and support 24 mA drive strength at 3.0 V.

The architecture enables bidirectional voltage translation: 3.3 V systems can safely drive and read 5 V signals via clamping diodes and robust ESD protection (HBM >2000 V), eliminating external level-shifting components in mixed-supply data paths.

FAQ

Can 74LVC827APW,112 operate with VCC = 1.2 V while driving 5 V-tolerant loads?

Yes. At VCC = 1.2 V, the device maintains full 5 V input/output tolerance per JESD8-7A compliance. Input thresholds scale to 0.9 × VCC (VIH min = 1.08 V), and outputs remain functional with VOH ≥ VCC − 0.2 V. However, propagation delay increases to 15.5 ns max, limiting use to low-frequency (<10 MHz) applications at this voltage.

What is the maximum capacitive load the outputs can drive while maintaining specified timing?

The datasheet specifies timing with CL = 30 pF (VCC ≤ 2.7 V) and CL = 50 pF (VCC ≥ 2.7 V). Driving loads >50 pF increases tpd and tdis proportionally due to RC delay; for 100 pF, measured tpd rises by ~3.2 ns at 3.3 V. Use series termination or reduce trace length if exceeding 50 pF.

How does dual OE control improve system-level design over single-OE buffers?

Dual OE inputs (OE1, OE2) allow independent gating of two logical groups - e.g., A0–A4 and A5–A9 - enabling partial bus isolation. This reduces switching noise, simplifies arbitration logic, and supports staggered enable sequences critical in high-reliability control systems where simultaneous bus transitions must be avoided.

Is 74LVC827APW,112 pin-compatible with older 74LVC827 variants in TSSOP24?

Yes. All 74LVC827 variants (including 74LVC827APW,112, 74LVC827PW,118, and 74LVC827BQ) share identical SOT355-1 pinout, electrical characteristics, and functional behavior. The suffix denotes process revision or packaging variant - not functional divergence - ensuring drop-in replacement across qualified versions.
