Note:
Stresses above those listed may cause permanent
damage to the device. This is a stress rating only and
functional operation of the device at these conditions, or at
any other condition above those indicated in the operations
section of this specification, is not implied. Exposure to
absolute maximum rating conditions for extended periods
may affect device reliability.

Mil-Std-883, Method 5005, Subgroup 1, 2, 3
Notes:
1. The following signals are CMOS compatible:
a) CMOS inputs: CS, ROMONLYN, T1, IRN, PIFN, CLK02N and CLKPCN
b) CMOS I/O signals: Microcode bus (M00-M19) and Microcode address bus (CC00-CC11)
2. The following signals are TTL compatible:
a) TTL inputs: Address/Data Bus (AD00-AD15), RESET and HOLDN
3. Worst case at T

4. CS and ROMONLYN inputs are provided for future microcode expansion and have internal pullup resistors. These
signals should be high for normal operation.
