SNx4HC595 8-Bit Shift Registers With 3-State Output Registers
1 Features
• 8-bit serial-in, parallel-out shift
• Wide operating voltage range of 2 V to 6 V
• High-current 3-state outputs can drive up to 15
LSTTL loads
• Low power consumption: 80-μA (maximum) ICC
• tpd = 13 ns (typical)
• ±6-mA output drive at 5 V
• Low input current: 1 μA (maximum)
• Shift register has direct clear
• On products compliant to MIL-PRF-38535,
all parameters are tested unless otherwise noted.
On all other products, production processing does
not necessarily include testing of all parameters.
2 Applications
• Network switches
• Power infrastructure
• LED displays
• Servers
3 Description
The SNx4HC595 devices 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 outputs. Separate clocks are provided for both
the shift and storage register. The shift register has
a direct overriding clear (SRCLR) input, serial (SER)
input, and serial outputs for cascading. When the
output-enable (OE) input is high, the outputs are in
the high-impedance state.
