SN74LS243 的特性
- Two-Way Asynchronous Communication Between Data Buses
- PNP Inputs Reduce D-C Loading
- Hysteresis (Typically 400 mV) at Inputs Improves Noise Margin
SN74LS243 的说明
These four-data-line transceivers are designed for asynchronous two-way communications between data buses. SN74LS243 can be used to drive terminated lines down to 133 .
SN54LS243 is characterized for operation over the full military temperature range of 55°C to 125°C. SN74LS243 is characterized for operation from 0°C to 70°C.
