Product Overview
Texas Instruments SN74ALS1035D packs six noninverting buffers into a 14-pin SOIC, each with an open-collector output, so an external pull-up resistor sets the high level. It is Advanced Low-power Schottky (ALS) bipolar TTL for 5 V logic.
Key Features
- Six independent noninverting buffers, Y = A
- Open-collector outputs; pull-up resistors required, off-state output up to 5.5 V
- Low-level output current: 24 mA
- Supply voltage: 4.5 V to 5.5 V
- Operating temperature: 0 C to 70 C
- 14-pin SOIC (TI D package), gull-wing leads, 8.65 x 6 mm
Applications
- Tying interrupt, reset or ready lines from several sources onto one wired-AND line with a single pull-up
- Sinking current for indicator LEDs or relay-driver inputs from 5 V TTL signals
- Repairing or rebuilding boards laid out for the SN74ALS1035 in SOIC
Frequently Asked Questions
The chips read ALS1035, not SN74ALS1035. Is that the right part?
Yes. TI prints only ALS1035 on the SOIC version of the SN74ALS1035; the full number appears on the DIP version.
Will it run from a 3.3 V supply?
No. ALS is 5 V bipolar TTL, specified for a 4.5 V to 5.5 V supply.
Can several outputs share one line?
Yes. Open-collector outputs only pull low, so several outputs can tie to one line with one pull-up resistor, and the line goes low when any output does.
Advanced Low-power Schottky was TI's way of keeping bipolar TTL quick while trimming its appetite for current. Hang one pull-up on a shared line and any of these six outputs can call it low.
