8-BIT SHIFT REGISTERS WITH 3-STATE OUTPUT REGISTERS

Check for Samples: SN54AHC595, SN74AHC595

FEATURES

DESCRIPTION

The ’AHC595 devices contain an 8-bit serial-in,

• Operating Range 2-V to 5.5-V V

parallel-out shift register that feeds an 8-bit D-type

• 8-Bit Serial-In, Parallel-Out Shift

storage register. The storage register has parallel 3-

• Latch-Up Performance Exceeds 100 mA Per

state outputs. Separate clocks are provided for both

JESD 78, Class II

the shift and storage registers. The shift register has

a direct overriding clear (SRCLR) input, serial (SER)

• ESD Protection Exceeds JESD 22

input, and a serial output for cascading. When the

– 2000-V Human-Body Model (A114-A)

output-enable (OE) input is high, all outputs, except

– 200-V Machine Model (A115-A)

QH′, are in the high-impedance state.

– 1000-V Charged-Device Model (C101)

Both the shift-register clock (SRCLK) and storage-

both clocks are connected together, the shift register

always is one clock pulse ahead of the storage
