SN74LS243 Description
These four-data-line transceivers are designed for asynchronous two-way munications between data buses. SN74LS243 can be used to drive terminated lines down to 133 Ω. SN54LS243 is characterized for operation over the full military temperature range of 55°C to 125°C.
SN74LS243 Key Features
- Two-Way Asynchronous munication Between Data Buses
- PNP Inputs Reduce D-C Loading
- Hysteresis (Typically 400 mV) at Inputs
