Key:
Hi-Z = High impedance
I = Input
O = Output
IO = Bi-Directional (Input/Output)
A = Analog
P = Power pin
C = CMOS level input
CD = CMOS level input with pull down resistor (typical value of 50ΚΩ at 3.3V)
CS = CMOS level Schmitt input
COx = CMOS output driver, x denotes driver type (1=2/-2mA, 2=6/-6mA @ 3.3V)
TSx = Tri-state CMOS output driver, x denotes driver type (1=2/-2mA, 2=6/-6mA @ 3.3V)
TSxU = Tri-state CMOS output driver with pull up resistor (typical value of 100ΚΩ at 3.3V), x denotes driver type
(1=2/-2mA, 2=6/-6mA @ 3.3V)
TSxD = Tri-state CMOS output driver with pull down resistor (typical value of 100ΚΩ at 3.3V), x denotes driver type
(1=2/-2mA, 2=6/-6mA @ 3.3V)
