What is 74LS145?
This is 1-of-10 Decoder/Driver, is designedto accept BCD inputsand provide appropriate outputs to drive 10-digit incandescent displays.All outputs remain off forall invalid binary input conditions.
Function: 1-of-10 decoder/driver open-collector
Package: DIP, SOIC 16 Pin Type
Manufacturer: Motorola, Freescale – > NXP Semiconductors
Image and Pinouts:
It is designedfor use as indicator/relaydrivers or as an open-collector logic circuit driver.Each of the high breakdown output transistors will sink up to 80 mA of current. Typical power dissipation is 35 mW. This device is fully compatible with all TTL families.

Q: What is the difference between a decoder and a demultiplexer?
A: A decoder is a digital circuit that converts coded inputs into coded outputs, while a demultiplexer is a digital circuit that takes a single input and selects one of several outputs based on the value of the input.
Q: What are some typical applications for the 74LS145?
A: This is commonly used in microprocessor systems to decode address or data bus lines. It can also be used in combination with other ICs to build complex logic circuits such as state machines or address decoders.
