SN74LS245 Description
These octal bus transceivers are designed for asynchronous two-way munication between data buses. The control-function implementation minimizes external timing requirements. The SNx4LS245 devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending on the logic level at the directioncontrol (DIR) input.
SN74LS245 Key Features
- 1 3-State Outputs Drive Bus Lines Directly
- PNP Inputs Reduce DC Loading on Bus Lines
- Hysteresis at Bus Inputs Improves Noise Margins
- Typical Propagation Delay Times Port to Port
