Product Summary

The SN74LS145N is a serial-in parallel-out shift register. The SN74LS145N is a high speed 8-Bit Serial-In Parallel-Out Shift Register. Serial data is entered through a 2-Input AND gate synchronous with the LOW to HIGH transition of the clock. The SN74LS145N features an asynchronous Master Reset which clears the register setting all outputs LOW independent of the clock. The SN74LS145N utilizes the Schottky diode clamped process to achieve high speeds and is fully compatible with all Motorola TTL products.
