The 74ACT138SCX from On Semiconductor is a high-speed 1-of-8 decoder/demultiplexer. This device is designed for applications requiring fast address decoding in bipolar memory systems. It accepts three binary weighted inputs (A0, A1, A2) and provides eight mutually exclusive active-LOW outputs (O0-O7) when enabled.
The device features multiple input enables, including two active-LOW (E1, E2) and one active-HIGH (E3), which allow for easy parallel expansion to create larger decoders, such as a 1-of-32 decoder using four of these devices and an inverter. The 74ACT138SCX can also function as an 8-output demultiplexer by utilizing one enable input as a data input.
This decoder/demultiplexer operates within a voltage range of 4.5V to 5.5V and has an operating temperature range of -40°C to 85°C. The outputs can source or sink up to 24 mA. The 74ACT138SCX is supplied in a 16-SOIC package, designed for surface mounting.
Key features include demultiplexing capability, multiple input enables for easy expansion, and active LOW mutually exclusive outputs. The ACT138 variant offers TTL compatible inputs.
