Product details

Overview

74ABT16827ADL,518 from NXP Semiconductors (formerly Philips) is a 20-bit non-inverting 3-state buffer/line driver in 56-pin SSOP package, delivering ±64 mA/–32 mA output drive, 1.4–1.7 ns propagation delay at 5 V, and operation across –40 °C to +85 °C for high-speed bus interface applications in industrial control backplanes.

For engineers reviewing the 74ABT16827ADL,518 datasheet, 74ABT16827ADL,518 pinout, 74ABT16827ADL,518 application, or 74ABT16827ADL,518 equivalent, key selection criteria include dual active-low output enables (1OE0/1OE1, 2OE0/2OE1), bus-hold-free input architecture, 4 pF input capacitance, and compatibility with 5 V TTL/CMOS logic families in wide data path buffering.

Technical Context

This BiCMOS buffer integrates low static current (500 µA in 3-state) with high-speed switching and robust noise immunity via multiple V_CC/GND pins. It supports transparent data flow when any output enable is asserted low and enters high-impedance state when all enables are high.

The device implements two independent 10-bit banks (Bank 1: A0–A9 → Y0–Y9; Bank 2: A0–A9 → Y0–Y9), each with dedicated NOR-type output enables (nOE1/nOE2 per bank), enabling selective bus segmentation without signal contention.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5 V to 5.5 V - Ensures compatibility with standard 5 V logic rails while tolerating supply droop during transient loading.
Propagation Delay	1.4 ns (t_PHL) / 1.7 ns (t_PLH) at V_CC = 5 V, C_L = 50 pF - Enables sub-2 ns timing margins in 500+ MHz bus cycles.
Output Drive	+64 mA (sourcing) / –32 mA (sinking) - Drives heavy capacitive loads (e.g., >100 pF traces or multiple TTL inputs) without external buffers.
Input Capacitance	4 pF - Minimizes loading on upstream drivers and preserves signal edge integrity in high-frequency routing.
Quiescent Current (3-State)	500 µA max at V_CC = 5.5 V - Reduces standby power in powered-down bus segments.
Operating Temperature	–40 °C to +85 °C - Validated for industrial-grade embedded systems including PLC I/O modules and telecom line cards.
ESD Protection	2000 V HBM, 200 V MM - Meets MIL-STD-883 requirements for handling robustness in manufacturing and field service.

Pinout & Package

74ABT16827ADL,518 is housed in a 56-pin plastic shrink small outline package (SSOP), body width 7.5 mm, drawing code SOT371-1, with exposed pad not present and lead finish matte tin.

Pin/Terminal	Circuit Role	Design Meaning
1, 28, 29, 56	1OE0, 1OE1, 2OE0, 2OE1	Active-low NOR enables - Asserting either OE per bank activates its 10-bit outputs; all high disables both banks simultaneously.
2–3, 5–6, 8–10, 12–14, 15–17, 19–21, 23–24, 26–27	1Y0–1Y9, 2Y0–2Y9	Non-inverting buffered outputs - Deliver rail-to-rail logic levels with controlled slew and high sink/source capability.
30–31, 33–34, 36–38, 40–43, 45–49, 51–52, 54–55	1A0–1A9, 2A0–2A9	Data inputs - Accept standard TTL/CMOS logic thresholds (V_IL ≤ 0.8 V, V_IH ≥ 2.0 V) with ±1 µA leakage.
4, 11, 18, 25, 32, 39, 46, 53	GND	Ground reference - Eight dedicated GND pins minimize ground bounce and improve noise rejection in high-speed switching.
7, 22, 35, 50	V_CC	Power supply - Four V_CC pins reduce supply impedance and suppress simultaneous switching noise across 20-bit output transitions.

Key Features

Feature	Design Value
Live insertion/extraction support	Enables hot-swap capability in modular backplane systems without damaging the 74ABT16827ADL,518 or adjacent components.
Power-up 3-State	Outputs remain in high-impedance until V_CC stabilizes above 2.1 V, preventing bus contention during power sequencing.
Multiple V_CC/GND pins	Four V_CC and eight GND pins reduce AC ground bounce and supply ripple, critical for maintaining signal integrity at >200 MHz.
Latch-up immunity	Exceeds 500 mA per JEDEC Std 17 - Guarantees robust operation under ESD or transient overvoltage stress conditions.
3-State output buffers	True high-impedance off-state (I_OZL/I_OZH ≤ ±10 µA) ensures no leakage current into disabled bus segments.

FAQ

What is the maximum clock frequency supported by the 74ABT16827ADL,518?

The 74ABT16827ADL,518 does not operate on a clock; it is an asynchronous buffer. Its 1.4 ns propagation delay enables reliable use in systems with data valid windows down to ~2 ns, supporting effective bus rates up to 500 MHz in well-terminated, low-skew layouts. Timing margin depends on load capacitance and PCB routing - verify with actual t_PLH/t_PHL measurements under your specific conditions using the 74ABT16827ADL,518.

Does the 74ABT16827ADL,518 include bus-hold circuitry on its inputs?

No, the 74ABT16827ADL,518 does not incorporate bus-hold functionality. That feature is exclusive to the 74ABTH16827A variant. Inputs of the 74ABT16827ADL,518 require external pull-up or pull-down resistors if left unconnected to prevent floating states - confirmed by Philips' 2002 product data distinguishing ABT (no bus-hold) from ABTH (with bus-hold).

What is the recommended layout practice for minimizing noise on the 74ABT16827ADL,518 power pins?

Use all four V_CC (pins 7, 22, 35, 50) and eight GND (pins 4, 11, 18, 25, 32, 39, 46, 53) pins with dedicated low-inductance vias to solid internal planes. Place 100 nF ceramic decoupling capacitors within 3 mm of each V_CC/GND pair. This layout strategy, specified in the 74ABT16827ADL,518 datasheet, reduces simultaneous switching noise and maintains <100 mV supply ripple under full 20-bit switching.

Can the 74ABT16827ADL,518 be used in a 3.3 V system?

No - the 74ABT16827ADL,518 is rated for 4.5 V to 5.5 V operation only. Applying 3.3 V violates the minimum V_CC specification and results in undefined output levels, increased propagation delay (>5 ns), and potential functional failure. For 3.3 V systems, consider the 74LVT16827 or similar LVT-family part - the 74ABT16827ADL,518 requires strict 5 V supply compliance.

How does the 74ABT16827ADL,518 handle power-up sequencing?

The 74ABT16827ADL,518 features power-up 3-State: outputs remain in high-impedance until V_CC exceeds 2.1 V, regardless of input or enable states. This prevents bus contention during power ramp-up. Once V_CC stabilizes above 4.5 V, normal operation begins - a behavior verified in the 74ABT16827ADL,518's "Power-up 3-State" feature and DC characteristics table.
