SN74LS145N BCD to decimal decoder/driver, 10 outputs, 5 V, DIL-16

Description These devices each contain an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. The storage register has parallel 3-state ('LS595) or open-collector ('LS596) outputs. seperater clocks are provided for both the shift register and the storage register. The shift register has a direct overriding clear, serial input, and serial output pins for cascading.

Both the shift register and storage register clocks are positive-edge triggered. If the user wishes to connect both clocks together, the shift register state will always be one clock pulse ahead of the storage register.
