11.1 SµΜMIT E Functional Pin Description
Legend for TYPE and ACTIVE fields1:
TO = TTL output
TTB = Three-state TTL bidirectional
CI = CMOS input
TUI = TTL input (internally pulled high)
AH = Active high
AL = Active low
TI = TTL input
TTO = Three-state TTL output
PGA = Pingrid Array
FP = Flatpack
[ ] = 132-lead Flatpack
Note:
1. All pins described as TTL use CMOS transistors that are designed
compatibility with TTL devices.
