The CD54HCT138F3A from RCA is a high-speed CMOS logic decoder/demultiplexer. It is designed for memory address decoding or data-routing applications, offering low power consumption comparable to low-power Schottky TTL logic.
Key electrical characteristics include a typical propagation delay of 13 ns at 5V and 15 pF. The device supports a wide operating temperature range from -55°C to 125°C. Standard outputs can drive up to 10 LSTTL loads, while bus driver outputs can drive up to 15 LSTTL loads.
This decoder features three binary select inputs (A0, A1, A2) and three enable inputs (E1, E2, E3) for easy cascading. Depending on the device type (138 or 238), outputs are normally high and go low, or normally low and go high when enabled.
The CD54HCT138F3A is available in a 16-lead CERDIP package, suitable for applications requiring robust performance across a broad temperature spectrum.
