SN54ALS1005 Datasheet, PDF (1/4 Pages) Texas Instruments – HEX INVERTING BUFFERS WITH OPEN-COLLECTOR OUTPUTS

• Buffer Versions of ′ALS05A
• Package Options Include Plastic
Small-Outline (D) Packages, Ceramic Chip
Carriers (FK), and Standard Plastic (N) and
Ceramic (J) 300-mil DIPs
description
These devices contain six independent inverting
buffers. They perform the Boolean function Y = A.
The open-collector outputs require pullup
resistors to perform correctly. These outputs can
be connected to other open-collector outputs to
implement active-low wired-OR or active-high
wired-AND functions. Open-collector devices are
often used to generate higher V_OH levels.
The SN54ALS1005 is characterized for operation
over the full military temperature range of – 55°C
to 125°C. The SN74ALS1005 is characterized for
operation from 0°C to 70°C.
