TECHNICAL DATA
KK74LV245
OCTAL BUS TRANSCEIVER; 3-State
The
KK74LV245
is a low-voltage Si-gate CMOS device and is pin and
function compatible with
KK74HCT245.
The
KK74LV245
is an octal transceiver featuring non-inverting 3-state
bus compatible outputs in both send and receive directions. The
KK74LV245
features an output enable (OE) input for easy cascading and a
send/receive (DIR) input for direction control. OE controls the outputs so
that the buses are effectively isolated.
