The CD54HCT138F3A from Harris Semiconductor is a high-speed silicon-gate CMOS decoder/demultiplexer. It is well-suited for memory address decoding or data-routing applications.
This device offers low power consumption characteristic of CMOS circuitry while maintaining speeds comparable to low-power Schottky TTL logic. It features three binary select inputs (A0, A1, A2) that determine which of the eight outputs is activated based on the enable inputs. The decoder has two active low and one active high enable inputs, facilitating the cascading of multiple decoders.
Key electrical characteristics include a typical propagation delay of 13 ns at 5V supply and 15 pF load. 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.
The CD54HCT138F3A is available in a 16-lead CERDIP package. Its HCT type designation indicates 4.5-V to 5.5-V operation and direct LSTTL input logic compatibility.
