DM74ALS1035M

Overview

The DM74ALS1035M is a hex non-inverting driver with open collector outputs manufactured by onsemi. It contains six independent drivers performing the logic identity function, requiring external pull-up resistors for proper operation. The device operates within a supply voltage range of 4.5 V to 5.5 V and an operating temperature range of 0 °C to +70 °C. Key electrical characteristics include a low-level output current (IOL) of 24 mA, a high-level output current (IOH) of 100 μA, and propagation delays of 53 ns (LOW-to-HIGH) and 21 ns (HIGH-to-LOW).

FAQ

Why are external pull-up resistors required?

The outputs are open collector type; they can only sink current. An external pull-up resistor is necessary to provide the HIGH logic level state.

What is the maximum low-level output current?

The maximum low-level output current (IOL) is specified as 24 mA.
