8-Bit Shift Register/Latch (3-state)
The TC74HC595A is a high speed 8-BIT SHIFT
REGISTER/LATCH fabricated with silicon gate C2MOS
technology.
It achieve the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
The TC74HC595A contains an 8-bit static shift register which
feeds an 8-bit storage register.
Shift operation is accomplished on the positive going transition
of the SCK input. The output register is loaded with the contents
of the shift register on the positive going transition of the RCK
input. Since RCK and SCK signal are independent, parallel
outputs can be held stable during the shift operation.
And, since the parallel outputs are 3-state, it can be directly
connected to 8-bit bus. This register can be used in
serial-to-parallel conversion, data receivers, etc.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Note: xxxFN (JEDEC SOP) is not available in
Japan.
