MM74HC589 8-Bit Shift Registers with Input Latches and 3-STATE Serial Output
MM74HC589
8-Bit Shift Registers
with Input Latches and 3-STATE Serial Output
General Description
The MM74HC589 high speed shift register utilizes
advanced silicon-gate CMOS technology to achieve the
high noise immunity and low power consumption of stan-
dard CMOS integrated circuits, as well as the ability to
drive 15 LS-TTL loads.
The MM74HC589 comes in a 16-pin package and consists
of an 8-bit storage latch feeding a parallel-in, serial-out 8-
bit shift register. Data can also be entered serially the shift
register through the SER pin. Both the storage register and
shift register have positive-edge triggered clocks, RCK and
SCK, respectively. SLOAD
pin controls parallel LOAD or
serial shift operations for the shift register. The shift register
has a 3-STATE output to enable the wire-ORing of multiple
devices on a serial bus.
The 74HC logic family is speed, function, and pin-out com-
patible with the standard 74LS logic family. All inputs are
protected from damage due to static discharge by internal
diode clamps to V
CC
and ground.
Features
■ 8-bit parallel storage register inputs
■ Wide operating voltage range: 2V–6V
■ Shift register has direct overriding load
■ Guaranteed shift frequency. . . DC to 30 MHz
■ Low quiescent current: 80
µA maximum (74HC Series)
■ 3-STATE output for ‘Wire-OR'
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

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 Dissipation temperature derating — plastic “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 (V
OH
, and V
OL
) occur for HC at 4.5V. Thus the 4.5V values should be used when
designing with this supply. Worst case V
IH
and V
IL
occur at V
CC
=5.5V and 4.5V respectively. (The V
IH
value at 5.5V is 3.85V.) The worst case leakage current
(I
IN
, I
CC
, and I
OZ
) occur for CMOS at the higher voltage and so the 6.0V values should be used.
