The AC/ACT138 is a high-speed 1-of-8 decoder/demultiplexer. This device is ideally suited for high-speed bipolar memory chip select address decoding. The multiple input enables allow parallel expansion to a 1-of-24 decoder using just three AC/ACT138 devices or a 1-of-32 decoder using four AC/ACT138 devices and one inverter.

• I_CC reduced by 50%
• Demultiplexing capability
• Multiple input enable for easy expansion
• Active LOW mutually exclusive outputs
• Outputs source/sink 24 mA
• ACT138 has TTL-compatible inputs
