Product details
Overview
74ABT827PW,118 from NXP Semiconductors is a 10-bit non-inverting 3-state buffer/line driver in TSSOP24 package, designed for high-speed bus interface buffering of wide data or address paths. It features dual NOR-type output enables (OE0, OE1), ±32 mA / +64 mA output drive, and operates across −40 °C to +85 °C. It delivers low propagation delay (tPLH/tPHL ≤ 4.8 ns) and supports flow-through pinout for microprocessor-oriented PCB layout.
For engineers reviewing the 74ABT827PW,118 datasheet, 74ABT827PW,118 pinout, 74ABT827PW,118 application, or 74ABT827PW,118 equivalent, key selection criteria include 3-state control flexibility, high-output-current capability for driving heavy capacitive loads, thermal robustness up to 150 °C junction temperature, and compatibility with 5 V TTL logic systems requiring fast, reliable signal buffering.
Technical Context
The 74ABT827PW,118 implements BiCMOS technology to achieve both low static power consumption and high-speed switching. Its dual active-low output enables allow independent control of two 5-bit subsets (Y0–Y4/Y5–Y9), enabling segmented bus management without external gating logic.
It supports power-up 3-state behavior and disables inputs during 3-state mode to prevent floating node contention. The device complies with JESD78B Class II latch-up protection (>500 mA) and meets HBM ESD immunity >2000 V per JESD22-A114F.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74ABT827DBR | SSOP24 package (SOT340-1), same electrical specs, 5.3 mm body width vs. 4.4 mm | Requires PCB footprint revision; slightly higher thermal resistance (θJA ≈ 110 K/W vs. 125 K/W) | Select when SSOP24 is already standardized in production and board space permits larger body width. |
| 74LVT827PW,118 | Lower VCC range (2.7–3.6 V), 3.3 V only; 32 mA output drive (vs. +64 mA); 5.5 ns max tPLH | Not suitable for 5 V systems; insufficient drive for legacy TTL loads or long traces | Choose only for new 3.3 V designs where lower power and reduced EMI outweigh drive and voltage compatibility needs. |

FAQ
What is the maximum operating supply voltage for the 74ABT827PW,118?
The 74ABT827PW,118 has an absolute maximum supply voltage (VCC) of +7.0 V, but its recommended operating range is strictly 4.5 V to 5.5 V. Operation outside this range may cause parametric shift or accelerated wear. The 74ABT827PW,118 is not rated for 3.3 V operation and will not meet AC/DC specifications below 4.5 V.
Does the 74ABT827PW,118 support hot insertion or live bus swapping?
The 74ABT827PW,118 supports controlled hot insertion due to its power-up 3-state feature and input disable during 3-state mode, which prevents bus contention during power ramp-up. However, it lacks explicit hot-swap circuitry (e.g., slew-rate limiting or back-drive protection), so external current-limiting resistors and sequencing controls are recommended for live-swapping applications involving the 74ABT827PW,118.
Can OE0 and OE1 be tied together for single-enable operation of the 74ABT827PW,118?
Yes, OE0 and OE1 can be connected to a common control signal, enabling all 10 outputs simultaneously. This configuration is electrically valid and commonly used in simplified bus designs. When tied together, the 74ABT827PW,118 behaves identically to a single 10-bit 3-state buffer - no timing or drive degradation occurs, and the function table remains fully applicable.
What is the input capacitance specification for the 74ABT827PW,118?
The 74ABT827PW,118 has a typical input capacitance (CI) of 4 pF per pin, measured at VI = 0 V or VCC. This low value minimizes loading on upstream drivers and supports high-frequency signal integrity - critical when cascading multiple 74ABT827PW,118 devices or driving long traces in high-speed digital systems.
Is the 74ABT827PW,118 compliant with RoHS and REACH regulations?
Yes, the 74ABT827PW,118 is manufactured in compliance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. NXP confirms lead-free terminations, halogen-free molding compound, and full substance declaration per IPC-1752A for the 74ABT827PW,118, supporting environmental compliance in commercial and industrial deployments.
