SN74ACT08DRE4

Overview

The SN74ACT08DRE4 is a quad 2-input positive-AND gate manufactured by Texas Instruments. It belongs to the 74ACT logic series, utilizing CMOS technology for high-speed operation with TTL-compatible inputs. The device operates within a supply voltage range of 4.5 V to 5.5 V and features low static power consumption. It provides symmetrical output drive capabilities with a low-level output current of 24 mA and a high-level output current of -24 mA. The typical propagation delay is 10 ns at 5 V. It is housed in a 14-pin SOIC package and supports an operating temperature range from -40°C to +85°C.

Feature Summary
