The CD54HCT139F3A from HAR is a High Speed CMOS Logic integrated circuit containing two independent binary to one of four decoders. Each decoder has an active-low enable input. Data on the select inputs determines which of the four normally high outputs will go low. For demultiplexer operation, the enable input serves as the data input. This device is suitable for memory decoding, data routing, and code conversion applications.
Key electrical characteristics include a wide operating temperature range of -55°C to 125°C and an operating voltage range of 4.5V to 5.5V for HCT types. It offers direct LSTTL input logic compatibility with VIL max of 0.8V and VIH min of 2V. Standard outputs provide a fanout of 10 LSTTL loads, while bus driver outputs offer a fanout of 15 LSTTL loads.
The CD54HCT139F3A is available in a 16-pin CDIP package. It is functionally the same as the CD4556B and is pin-compatible with it. This component is designed for applications requiring reliable decoding and demultiplexing functions within demanding environmental conditions.
