HD74HC595
8-bit Shift Register/Latch (with 3-state outputs)
REJ03D0634-0200 (Previous ADE-205-514) Rev.2.00 Mar 30, 2006
Description
This device each contains 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 outputs. Separate 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.
Features
* High Speed Operation: tpd (RCK to Q) = 17 ns typ (CL = 50 pF) * High Output Current: Fanout of 15 LSTTL Loads (QA to QH outputs) * Wide Operating Voltage: VCC = 2 to 6 V * Low Input Current: 1 A max * Low Quiescent Supply Current: ICC (static) = 4 A max (Ta = 25C) * Ordering Information
