The 74HC245D,653 is an Integrated Circuit (IC) component that belongs to the 74HC series of ICs, specifically the non-inverting 3-state buffer/line driver. It is a versatile and widely used component in digital electronic circuits. Below are the key features and an overview of the 74HC245D,653:
1. Overview:
- The 74HC245D,653 is an octal (8-channel) bus transceiver IC.
- It facilitates bidirectional voltage level translation between different logic levels.
- It provides controlled output for driving highly capacitive loads or bus lines.
- The buffer enables the control of the direction of data flow from the A-bus to the B-bus or vice versa.
- It operates on a supply voltage range of 2V to 6V.
- The device can be used as an individual transceiver or as a part of a bus-oriented system.
- It is widely used in various applications like memory interfacing, data communication, and general-purpose switch applications.
2. Key Features:
- 8-bit bidirectional bus interface.
- Independent 3-state control for each channel using OE (Output Enable) and DIR (Direction) pins.
- Schmitt-trigger action on all inputs ensures minimal noise sensitivity.
- Allows direct interface with TTL levels.
- High-speed operation with a propagation delay of just a few nanoseconds
