Notes: 1. H = High voltage level, L = Low voltage level, X = Don’t care, ↑ = Low-to-High transition
2. The data output functions may be enabled or disabled by various signals at the xOE or xDir inputs. Data input functions
are always enabled, i.e. data at the bus pins will be stored on every LOW-to-HIGH transition on the clock inputs.
Absolute Maximum Ratings*
Operating Temperature........................ 0°C to +70°C
Storage Temperature ...................... -65°C to +150°C
Voltage on any Pin
with Respect to Ground................. -2.0 V to +7.0 V(1)
Maximum Operating Voltage.............................. 6.0V
5.0 Volt DC Characteristics
*NOTICE: Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional operation
of the device at these or any other conditions beyond those
indicated in the operational sections of this specification is
not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
Notes:
1. Minimum voltage is -0.6 V dc which may
undershoot to -2.0 V for pulses of less than 20 ns.
Maximum output pin voltage is VCC +0.75 V dc
which may overshoot to +7.0 V for pulses of less
than 20 ns.
Applicable over recommended operating range from Ta = 0°C to +70°C, VCC = +5.0V +/- 5% (unless otherwise noted)
