SCBS034B – JULY 1989 – REVISED NOVEMBER 1993
• Open-Collector Version of ′BCT244
• Open-Collector Outputs Drive Bus Lines or
Buffer Memory Address Registers
• ESD Protection Exceeds 2000 V Per
MIL-STD-883C Method 3015
• Packages Options Include Plastic
Small-Outline (DW) Packages, Ceramic
Chip Carriers (FK) and Flatpacks (W), and
Standard Plastic and Ceramic 300-mil DIPs
(J, N)
description
These octal buffers and line drivers are designed
specifically to improve both the performance and
density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and
transmitters.
The ′BCT760 is organized as two 4-bit buffers/line
drivers with separate output-enable (OE) inputs.
When OE
A inputs to the Y outputs. When OE is high, the
outputs are in the high-impedance state.
The SN54BCT760 is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74BCT760 is characterized for
operation from 0°C to 70°C.

‡
Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The negative input voltage rating may be exceeded if the input clamp current rating is observed.
