SN74LS652DW

The SN74LS652DW from Texas Instruments is an octal bus transceiver designed for high-speed data transmission. This device features 8 channels and non-inverting logic, making it suitable for various bus interface applications.

Key electrical characteristics include an operating voltage range of 4.75V to 5.25V, with output currents of 15mA and 24mA for high and low states, respectively. The output type is 3-state, providing flexibility in bus management. The device operates within a temperature range of 0°C to 70°C.

Packaged in a 24-SOIC format, the SN74LS652DW is designed for surface mounting. Its features include independent registers and enables for A and B buses, multiplexed real-time and stored data options, and a choice of true and inverting data paths. This makes it a versatile component for systems requiring efficient data bus control and transfer.

This transceiver integrates bus transceiver circuits, D-type flip-flops, and control circuitry. Enable signals GAB and G\BA control transceiver functions, while SAB and SBA pins select between real-time or stored data transfer. A low input level on these pins selects real-time data, and a high level selects stored data.
