■ Latch-up performance exceeꢀs 500mA
for use as an interface between a 3.3K bus anꢀ a
2.5K or 1.±K bus in a mixeꢀ 3.3K/1.±K, 3.3K/2.5K
anꢀ 2.5K/1.±K supply systems, it achieves high
speeꢀ operation while maintaining the CMOS low

■ ESD protection for A-port:
This ꢀevice is intenꢀeꢀ for two-way asynchronous
communication between ꢀata buses anꢀ the
ꢀirection of ꢀata transmission is ꢀetermineꢀ by
CMD-ꢀir/ DATA0-ꢀir/ DAT123-ꢀir inputs. The B-
port interfaces with the 3K bus, the A-port with the
2.5K anꢀ 1.±K bus.
HBM > ±2ꢁK (MIL STD ±±3 methoꢀ 3015);
■ R HS Compliant for µTFBGA25 Pacꢁage

All inputs are equippeꢀ with protection circuits
against static ꢀischarge, giving them ±2ꢁK (on A-
siꢀe except CD anꢀ WP pins) anꢀ ±15ꢁK on (B
siꢀe, CD anꢀ WP pins) ESD immunity anꢀ
transient excess voltage. See the section on
