Product details

Overview

SN74BCT2410DW from Texas Instruments is an 11-bit noninverting BiCMOS buffer/line driver designed to drive MOS DRAMs up to 4 Mbit and wide data buses with parity. It features dual active-low output-enable inputs (OE1, OE2) with internal AND logic, 33-Ω integrated series output resistors, 1 mA source / 12 mA sink capability per output, and operation across 0°C to 70°C.

For engineers reviewing the SN74BCT2410DW datasheet, SN74BCT2410DW pinout, SN74BCT2410DW application, or SN74BCT2410DW equivalent, key selection criteria include its 11-channel noninverting drive architecture, built-in termination for signal integrity on high-speed memory buses, dual enable control logic, and SOIC-28 package compatibility with legacy DRAM interface layouts.

Technical Context

The SN74BCT2410DW implements a dual-gated output-enable structure where both OE1 and OE2 must be low to activate all 11 Y outputs; either high forces all outputs into high-impedance state. Its BiCMOS design reduces ICCZ quiescent current while maintaining TTL-compatible input thresholds (VIL = 0.8 V, VIH = 2 V) and CMOS-level output drive strength.

Each output integrates a 33-Ω series resistor to suppress transmission-line overshoot/undershoot without external components, and multiple ground pins minimize switching noise in parallel bus environments. The device operates strictly within 4.5 V–5.5 V supply range and is not rated for 3.3 V or mixed-voltage operation.

Key Specifications

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74BCT240DW	Inverting output logic; otherwise identical pinout, drive strength, and specs	Requires logic inversion in upstream signal path or downstream load	Select when bus polarity inversion is acceptable or required by system architecture
SN74ACT244N	Octal (8-bit), not 11-bit; ACT logic family - higher speed (tPD ≈ 6 ns), lower ICCZ, but no integrated 33-Ω resistors	Requires two devices plus external termination for 11-bit coverage; better for 3.3 V–5 V mixed systems	Choose for higher-speed designs where discrete termination is acceptable and pin count allows dual-package layout

Compared with SN74BCT2410DW, SN74BCT240DW provides identical drive and packaging but inverted logic, making it suitable only where polarity reversal is tolerable; SN74ACT244N offers faster timing and lower power but lacks on-die termination and native 11-bit width, increasing BOM count and layout complexity for equivalent functionality.

FAQ

What is the function of the dual output-enable inputs OE1 and OE2 on the SN74BCT2410DW?

The SN74BCT2410DW uses internal AND logic between OE1 and OE2: both must be low to enable all 11 Y outputs. If either is high, all outputs enter high-impedance state. This allows hierarchical control - for example, OE1 tied to a subsystem enable and OE2 to a global bus grant signal - ensuring precise, glitch-free bus isolation in complex memory systems using the SN74BCT2410DW.

Does the SN74BCT2410DW support 3.3 V operation?

No, the SN74BCT2410DW is specified only for 4.5 V to 5.5 V supply operation and is not 3.3 V tolerant. Its input thresholds (VIH = 2 V, VIL = 0.8 V) and output drive characteristics are optimized for 5 V TTL/CMOS systems. Using it with 3.3 V logic may result in undefined behavior or damage; the SN74BCT2410DW requires a clean 5 V supply rail.

Are the 33-Ω series resistors on the SN74BCT2410DW outputs internal or external?

The 33-Ω series resistors on the SN74BCT2410DW outputs are monolithically integrated within the die - no external components are needed. This internal termination reduces PCB space, eliminates solder joint variability, and ensures consistent impedance matching for improved signal integrity on DRAM address and data buses driven by the SN74BCT2410DW.

What is the maximum output sink current per channel for the SN74BCT2410DW?

The SN74BCT2410DW is rated for 12 mA low-level output current (IOL) per Y pin under recommended operating conditions (VCC = 4.5 V, TA = 25°C). This value ensures reliable driving of TTL inputs and terminated transmission lines. Exceeding 12 mA risks violating VOL specifications or exceeding absolute maximum ratings - the SN74BCT2410DW must not be loaded beyond this limit per output.

Is the SN74BCT2410DW pin-compatible with other 28-pin SOIC logic buffers?

The SN74BCT2410DW has a unique 28-pin SOIC (DW) pinout optimized for 11-bit buffering with dual enables and triple ground pins - it is not pin-compatible with octal (e.g., SN74BCT244) or hex (e.g., SN74BCT257) devices. Layout reuse requires exact matching of A1–A11, Y1–Y11, OE1/OE2, VCC, and GND positions defined in the SN74BCT2410DW datasheet.
