MM74HC595 — 8-Bit Shift Register with Output Latches
MM74HC595
8-Bit Shift Register with Output Latches
Features
Low Quiescent current: 80µA Maximum
(74HC Series)
Low Input Current: 1µA Maximum
8-Bit Serial-In, Parallel-Out Shift Register with
Storage
Wide Operating Voltage Range: 2V–6V
Cascadable
Shift Register has Direct Clear
Guaranteed Shift Frequency: DC to 30MHz
Description
The MM74HC595 high-speed shift register utilizes
advanced silicon-gate CMOS technology. This device
possesses the high noise immunity and low power
consumption of standard CMOS integrated circuits, as
well as the ability to drive 15 LS-TTL loads.
This device contains an eight-bit serial-in, parallel-out,
shift register that feeds an eight-bit D-type storage
register. The storage register has eight 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
(standard) pins for cascading. Both the shift register
and storage register use positive-edge triggered clocks.
If both clocks are connected together, the shift register
state is one clock pulse ahead of the storage register.
The 74HC logic family is speed, function, and pin-out
compatible with the standard 74LS logic family. All
inputs are protected from damage due to static
discharge by internal diode clamps to VCC and ground.

Absolute Maximum Ratings(1)
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device
reliability. The absolute maximum ratings are stress ratings only.

Note:
3. For a power supply of 5V ±10%, the worst-case output voltages (VOH, and VOL) occur for HC at 4.5V. The 4.5V
values should be used when designing with this supply. Worst-case VIH and VIL occur at VCC = 5.5V and 4.5V,
respectively; VIH value at 5.5V is 3.85V. The worst-case leakage current (IIN, ICC, and IOZ) occurs for CMOS at
the higher voltage; so the 6.0V values should be used.
