(20µA in High and Low states)
•Octal bidirectional bus interface
•Common Output Enable for both Transmit and Receive modes
•Open collector outputs sink 64mA
•Non-inverting
INPUT AND OUTPUT LOADING AND FAN-OUT TABLE
PINS DESCRIPTION
A0 - A7, B0 - B7 Data inputs 1.0/0.033 20µA/20µA
T/R Transmit/Receive input 2.0/0.067 40µA/40µA
OE Output Enable inputs 2.0/0.067 40µA/40µA
A0 - A7 Data outputs OC/40 OC/24mA
B0 - B7 Data outputs OC/106.7 OC/64mA
NOTE: One (1.0) FAST unit load is defined as: 20µA in the High state and 0.6mA in the Low state. OC = Open Collector.

Definitions
Short-form specification — The data in a short-form specification is extracted from a full data sheet with the same type number and title. For
detailed information see the relevant data sheet or data handbook.
Limiting values definition — Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one
or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or
at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended
periods may affect device reliability.
Application information — Applications that are described herein for any of these products are for illustrative purposes only. Philips
Semiconductors make no representation or warranty that such applications will be suitable for the specified use without further testing or
modification.
