The TLC59212 is an 8-bit open-collector driver with latch designed for 5-V VCC operation. These circuits are positive-edge-triggered D-type flip-flops with a direct clear (CLR) input. Information at the data (D) input meeting the setup time requirements is transferred to the Y output on the positive-going edge of the clock (CLK) pulse. Clock triggering occcurs at a particular voltage level and is not directly related to the transition time of the positive-going pulse. When CLK is at either the high or low level, the D-input has no effect at the output.
