MM74HC573 3-STATE Octal D-Type Latch
MM74HC573
3-STATE Octal D-Type Latch
General Description
The MM74HC573 high speed octal D-type latches utilize
advanced silicon-gate P-well CMOS technology. They pos-
sess the hi gh noise immun ity an d low power consu mption
of standard CMO S inte grate d c ircuits, a s we ll as th e ability
to drive 15 LS-TTL loads. Due to the large output drive
capability and the 3-STATE feature, these de vices are ide-
ally suited for interfacing with bus lines in a bus organized
system.
When the LATCH ENABLE(LE) input is HIGH, the Q out-
puts will follow the D inputs. When the LATCH ENABLE
goes LOW, data at the D inputs will be r etained at the out-
puts until LATCH ENABLE returns HIGH again. When a
HIGH logic level is applied to the OUTPUT CONTROL OC
input, all outputs go to a HIGH impedance state, regardless
of what signals are present at the other inputs and the state
of the storage elements.
The 74HC logic family is speed, function and pinout com-
patible with the standard 74LS logic family. All inputs are
protected from damage due to static discharge by inte rnal
diode clamps to VCC and ground.
Features
Typical propagation delay: 18 ns
Wide operating voltage range: 2 to 6 volts
Low input current: 1 µA maximum
Low quiescent current: 80 µA maximum ( 74HC S erie s)
Compatible with bus-oriented systems
Output drive capability: 15 LS-TTL loads
Ordering Code:
Devices also available in Tape and Reel. Specify by appending th e s uffix let t er “X” to the o rdering code.

DC Electrical Character istics (Note 4)
Note 4: For a po wer supp ly of 5 V ±10% t he worst -case ou tput vol tages (VOH, and VOL) occu r for HC a t 4.5V. Thus the 4.5V v alues sho uld be used wh en
designing with this su pply. Worst-case VIH and VIL occur at VCC = 5.5V and 4.5V respectively. (The VIH va lue at 5.5V is 3. 85V.) T he worst-c as e leakage cur-
rent (IIN, ICC, and IOZ) occur for CMOS at the hi gher volta ge and so th e 6. 0V values s hould be used.
