0 = Low Level
Z = High Impedance on Both CMOS and TTL sides.
1 = High Level
X = Don’t Care
NOTE: An important caveat that is applicable to CMOS devices in
general is that unused inputs should never be left floating. This rule
applies to inputs connected to a three-state bus. The need for
external pull-up resistors during three-state bus conditions is
eliminated by the presence of regenerative latches on the following
HS-3374RH pins: A0 - 7.
The functional block diagram depicts one of these pins with the
regenerative latch. When the CMOS driver assumes the high
impedance state, the latch holds the bus in whatever logic state
(high or low) it was before the three-state condition. A transient
drive current of
±
1.5mA at VDD/2
±
0.5V for 10ns is required to
switch the latch. Thus, CMOS device inputs connected to the bus
are not allowed to float during three-state conditions.
* WARNING: Do not activate the Disable input by hardwiring to any
TTL input pins. This is an incorrect mode of operation.
