EXTERNAL CRYSTAL CONNECTIONS
272145±13
NOTE:
Keep oscillator components close to chip and use
short, direct traces to XTAL1, XTAL2 and VSS. When
using ceramic crystals, C1 e 20 pF, C2 e 20 pF.
When using ceramic resonators consult manufacturer
for recommended capacitor values.
EXTERNAL CLOCK CONNECTIONS
272145±14
NOTE:
Required if TTL driver used.
Not needed if CMOS driver is used.
AC TESTING INPUT, OUTPUT WAVEFORMS
272145±11
AC Testing inputs are driven at 2.4V for a Logic ``1'' and 0.45V for
a Logic ``0'' Timing measurements are made at 2.0V for a Logic
``1'' and 0.8V for a Logic ``0''.
FLOAT WAVEFORMS
272145±12
For Timing Purposes a Port Pin is no Longer Floating when a
150 mV change from Load Voltage Occurs, and Begins to Float
when a 150 mV change from the Loaded VOH/V OL Level occurs;
IOL/I OH e g15 mA.
EXPLANATION OF AC SYMBOLS
Each symbol is two pairs of letters prefixed by ``T'' for time. The characters in a pair indicate a signal and its
condition, respectively. Symbols represent the time between the two signal/condition points.
Conditions:
H - High
L - Low
V - Valid
X - No Longer Valid
Z - Floating
Signals:
A - Address
B - BHE
C - CLKOUT
D - DATA
G - Buswidth
H - HOLD
HA - HLDA
L -
ALE/ADV
BR - BREQ
R - RD
W - WR/WRH /WRL
X - XTAL1
Y - READY
Q - Data Out
