Product details

Overview

SN74ABT5400ADW from Texas Instruments is an 11-bit noninverting 3-state line/memory driver with dual active-low output-enable inputs, designed for high-density memory address and bus-oriented applications. It operates from 4.5 V to 5.5 V, supports –40°C to 85°C, delivers ±12 mA output drive, and integrates 25-Ω series output resistors to suppress overshoot/undershoot without external components.

For engineers reviewing the SN74ABT5400ADW datasheet, SN74ABT5400ADW pinout, SN74ABT5400ADW application, or SN74ABT5400ADW equivalent, key selection criteria include its 11-channel 3-state buffering capability, EPIC-II^B BiCMOS process for low power, latch-up immunity >500 mA, and DW-package compatibility with standard SOIC-24 footprints.

Technical Context

This device implements a dual-gated 3-state control architecture: OE1 and OE2 feed a 2-input AND gate, so either input high forces all 11 outputs into high-impedance mode. Outputs are designed for bidirectional bus interfacing with TTL-compatible input thresholds (V_IL = 0.8 V, V_IH = 2 V) and rail-to-rail switching under 5-V supply.

Its EPIC-II^B BiCMOS process enables typical propagation delays of 2–6.3 ns (t_PLH/t_PHL) and enable/disable times as low as 1.5 ns (t_PHZ/t_PLZ) at CL = 50 pF, while maintaining low ground bounce (V_OLP < 1 V) and undershoot (V_OLV < 0.5 V) at V_CC = 5 V and T_A = 25°C.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5 V to 5.5 V - ensures compatibility with standard 5-V TTL and mixed-voltage bus systems.
Output Drive	±12 mA - sufficient to directly drive 50-pF loads across 11 channels without external buffers.
Propagation Delay	1.5–6.3 ns - enables high-speed address/data latching in memory subsystems up to ~100 MHz.
3-State Enable Time	1.5–8.8 ns - supports fast bus turnaround in multiplexed shared-bus architectures.
Input Thresholds	V_IL = 0.8 V, V_IH = 2 V - guarantees reliable recognition of TTL-level logic signals.
Output Series Resistance	25 Ω (integrated) - eliminates need for external termination resistors on PCB traces.
Latch-Up Immunity	>500 mA per JESD-17 - meets military-grade robustness requirements for industrial environments.

Pinout & Package

SN74ABT5400ADW is supplied in a 24-pin plastic small-outline (DW) package with 300-mil body width and standard SOIC footprint. Pin spacing is 0.050 inch (1.27 mm), compatible with automated assembly and IPC-7351B SOIC24_300.

Pin/Terminal	Circuit Role	Design Meaning
1–11, 13, 16–20, 22–24	Y1–Y11 Output	Noninverting buffered outputs with 25-Ω series resistance; each independently controllable via OE1/OE2.
12, 15	OE1, OE2	Active-low 3-state enable inputs; AND logic requires both low for output assertion.
14, 21, 28	D1–D11 Input	Noninverting data inputs; TTL-compatible thresholds ensure interoperability with legacy logic families.
7, 8, 25, 26	GND	Four dedicated ground pins minimize ground bounce and improve noise margin across all 11 channels.
23, 27	V_CC	Two separate 5-V supply pins reduce IR drop and support stable operation under dynamic load switching.

Key Features

Feature	Design Value
Integrated 25-Ω output series resistors	Eliminates external termination components and reduces PCB layout complexity for high-speed buses.
EPIC-II^B BiCMOS process	Reduces static power consumption versus standard bipolar TTL while retaining speed and drive strength.
High latch-up immunity (>500 mA)	Enables reliable operation in electrically noisy industrial and automotive environments per JESD-17.
Low ground bounce (V_OLP < 1 V)	Maintains signal integrity during simultaneous output switching, critical for multi-bit address/data buses.
Dual active-low 3-state control	Provides flexible bus arbitration: either OE1 or OE2 high disables all outputs, simplifying system-level enable logic.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 11-bit 3-state buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74ABT244N	8-bit (not 11-bit); single OE input; same EPIC-II^B process and 25-Ω resistors.	Suitable only where channel count reduction is acceptable and bus width is ≤8 bits.	Select when system uses 8-bit data paths and requires identical timing/power characteristics.
SN74LVC541APWR	3.3-V only (1.65–3.6 V); no integrated series resistors; CMOS process; lower drive (±24 mA).	Requires external termination and level-shifting for 5-V bus integration; unsuitable for direct 5-V TTL replacement.	Choose only for new 3.3-V designs prioritizing ultra-low power over backward compatibility.

Compared with SN74ABT244N and SN74LVC541APWR, the SN74ABT5400ADW uniquely provides 11-bit width, dual OE control, and integrated 25-Ω termination in a 5-V system-making it irreplaceable for legacy memory address expansion without redesigning bus topology or adding discrete resistors.

FAQ

What is the operating temperature range for SN74ABT5400ADW?

The SN74ABT5400ADW is characterized for operation from –40°C to +85°C, making it suitable for commercial and industrial environments. This range is distinct from the SN54ABT5400A variant, which supports –55°C to +125°C for military applications. The SN74ABT5400ADW's thermal performance is validated per JEDEC JESD51, with θ_JA = 78°C/W in the DW package.

Does SN74ABT5400ADW require external pull-up resistors on OE pins?

Yes - to ensure outputs remain in high-impedance state during power-up or power-down, OE1 and OE2 should be tied to V_CC through pull-up resistors. The minimum resistor value depends on the current-sinking capability of the driving source; TI recommends evaluating based on the driver's I_OL rating and desired rise time. No internal pull-ups are provided on SN74ABT5400ADW.

How does the dual OE architecture of SN74ABT5400ADW affect bus control?

The SN74ABT5400ADW uses a 2-input AND gate for 3-state control: both OE1 and OE2 must be low for outputs to drive. If either is high, all 11 Y outputs go high-impedance. This allows hierarchical bus arbitration - for example, OE1 controlled by CPU and OE2 by DMA controller - ensuring exclusive bus access without external logic gates.

Can SN74ABT5400ADW drive 50-pF loads reliably at 100 MHz?

While SN74ABT5400ADW is not rated for continuous 100-MHz clock operation, its propagation delay (1.5–6.3 ns) and enable/disable timing (1.5–8.8 ns) support reliable 11-bit address/data latching in systems with ≥10-ns cycle times. For sustained 100-MHz bus operation, signal integrity depends on trace length, termination, and load capacitance - the integrated 25-Ω resistors help manage reflections on properly routed 50-pF nets.

Is SN74ABT5400ADW pin-compatible with other ABT-series drivers?

No - SN74ABT5400ADW is a unique 11-bit configuration in a 24-pin DW package. It is not pin-compatible with 8-bit variants like SN74ABT244 or 16-bit devices such as SN74ABT162244. Its pinout (including dual OE, four GND, and two V_CC pins) is specific to the 11-bit topology and cannot be substituted without PCB revision.
