MM74HC595 8-Bit Shift Regi sters with Output Latches
MM74HC595
8-Bit Shift Registers with Outpu t Latches
General Description
The MM74HC595 high speed shift register utilizes
advanced s ilicon- gate CM OS te chnology. This device pos-
sesses the high noise immunity and low power consump-
tion of standard CMOS integrated circuits, as well as the
ability to drive 15 LS-TTL loads.
This device contains an 8-bit serial-in, parallel-out shift reg-
ister that feeds an 8-bit D-type storage register. The stor-
age register has 8 3-STATE outputs. Separate clocks are
provide d for both the sh ift reg ister and the stora ge r egister.
The shift register has a direct-over riding clea r, ser ial input,
and serial output (standard) pins for cascading. Both the
shift register and storage register use positive-edge trig-
gered clocks. If both clocks are connected together, the
shift register state will always be one clock pulse ahead of
the storage register.
The 74H C log i c fam ily i s sp ee d, fu ncti o n, a nd pin- ou t com -
patible with the standard 74LS logic family. All inputs are
protect ed from damage d ue to static d ischarge by inter nal
diode clamps to VCC and ground.
Features
Low quiescent current: 80 µA maximum ( 74HC S erie s)
Low input current: 1 µA maximum

Absolute Maximum Ratings(Note 1)
(Note 2) Recommended Operating
Conditions
Note 1: Absolute Maximum Ratings are those values beyond which dam-
age to the device may occur.
Note 2: Unless otherwise specified all voltages are referenced to ground.
Note 3: Power Dis sipation te mperature d erating plas tic N package:
12 mW/°C from 65°C to 85°C.
DC Electrical Characteristics (Note 4)
Note 4: For a power supply of 5V ±10% the worst case output voltages (VOH, and VOL) occ ur for HC at 4.5V. Thus the 4. 5V valu es shou ld be u sed when
designi ng with t his s upply. Worst c as e VIH and VIL occur at VCC = 5.5V and 4.5V respectively. (The VIH value at 5.5V is 3.85V.) The worst case leakage cur-
rent (IIN, ICC, and IOZ) occur fo r C M OS at the h igher vol ta ge and so th e 6. 0V values s hould be used.
