NXP Semiconductors 74ABT827D,623

Overview

74ABT827D,623 from NXP Semiconductors is a 10-bit non-inverting 3-state buffer/line driver in SO24 package, delivering high-speed bus interface buffering with ±32 mA / +64 mA output drive, 4.5–5.5 V supply operation, and −40 °C to +85 °C temperature range for wide data/address path applications.

For engineers reviewing the 74ABT827D,623 datasheet, 74ABT827D,623 pinout, 74ABT827D,623 application, or 74ABT827D,623 equivalent, key selection criteria include dual NOR-type output enables (OE0/OE1), flow-through pinout architecture, power-up 3-state behavior, latch-up immunity >500 mA, and HBM ESD >2000 V - all critical for reliable microprocessor bus interfacing.

Technical Context

The 74ABT827D,623 implements BiCMOS logic to achieve low static/dynamic power dissipation while maintaining propagation delays as low as 1.1 ns (tPLH/tPHL) and fast 3-state enable/disable times (tPZH ≤ 6.3 ns, tPZL ≤ 6.9 ns at −40 °C to +85 °C). Its dual active-low output enables (OE0, OE1) support independent control of output groups.

Inputs are disabled during 3-state mode, and the device features power-off leakage current ≤ ±100 µA at VCC = 0 V. Static characteristics include VIH ≥ 2.0 V, VIL ≤ 0.8 V, VOL ≤ 0.55 V at IOL = 64 mA, and VOH ≥ 2.5 V at IOH = −3 mA - ensuring robust TTL/CMOS compatibility.

FAQ

What is the maximum operating supply voltage for the 74ABT827D,623?

The 74ABT827D,623 has an absolute maximum supply voltage (VCC) of +7.0 V per its limiting values table, but the recommended operating range is strictly 4.5 V to 5.5 V. Operating outside this range risks violating static and dynamic specifications, including output voltage levels, propagation delay, and latch-up immunity - all verified only within the 4.5–5.5 V window per NXP's characterization data.

Does the 74ABT827D,623 support independent control of output groups?

Yes, the 74ABT827D,623 provides two independent active-low output enables: OE0 controls Y0–Y4, and OE1 controls Y5–Y9. This allows segmented bus isolation - for example, enabling address bits A0–A4 while holding A5–A9 in high-impedance during partial memory access - a feature confirmed in the function table and pin description of the official NXP datasheet Rev. 5.

Is the 74ABT827D,623 pin-compatible with other ABT-series 10-bit buffers?

No - the 74ABT827D,623 has a unique flow-through pinout (A0–A9 on pins 2–11, Y9–Y0 on pins 14–23) optimized for microprocessor bus routing. Other ABT 10-bit buffers like 74ABT162244 use different pin assignments and output enable configurations. Pin compatibility must be verified per-package pin diagram; no generic ABT-family pin mapping applies to 74ABT827D,623.

What is the significance of "power-up 3-state" in the 74ABT827D,623?

"Power-up 3-state" means the 74ABT827D,623 outputs remain in high-impedance until VCC reaches a valid operating level - preventing bus contention during power ramp-up. This behavior is intrinsic to the internal power-on reset circuitry and is guaranteed across −40 °C to +85 °C, eliminating need for external reset sequencing in systems using 74ABT827D,623 for critical bus isolation.

Can the 74ABT827D,623 drive 50 pF loads while maintaining timing specs?

Yes - NXP's dynamic characteristics test conditions explicitly specify CL = 50 pF (including jig and probe capacitance) for measuring tPLH, tPHL, and 3-state delays. The 74ABT827D,623 achieves tPLH/tPHL ≤ 4.8 ns and tPZH/tPZL ≤ 6.9 ns under these exact conditions at VCC = 5.0 V ± 0.5 V and −40 °C to +85 °C, confirming full compliance with 50 pF bus loading requirements.
