(Pin 1):
Positive Supply, 5V to
±
5%. Bypass with
0.1
μ
F ceramic capacitor.
R (Pin 2):
Receiver Output. If A
≥
B by 300mV, then R will
be high. If A
≤
B by 300mV, then R will be low.
D (Pin 3):
Driver Input. Controls the states of the Y and Z
outputs. Do not float.
GND
(Pin 4):
Ground.
Y (Pin 5):
Noninverting Driver Output.
Z (Pin 6):
Inverting Driver Output.
B (Pin 7):
Inverting Receiver Input.
A (Pin 8):
Noninverting Receiver Input.
LTC1687
NC (Pins 1, 8, 13):
No Connection.
R (Pin 2):
Receiver Output. If A
≥
B by 300mV, then R will
be high. If A
≤
B by 300mV, then R will be low.
RE (Pin 3):
Receiver Enable. RE = low enables the receiver.
RE = high forces receiver output into high impedance
state. Do not float.
