The
KK
74LV245 is a low-voltage Si-gate CMOS device and is pin and
function compatible with
KK
74HCT245.
The
KK
74LV245 is an octal transceiver featuring non-inverting 3-state
bus compatible outputs in both send and receive directions. The
KK
74LV245 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.
Output voltage levels are compatible with input levels of CMOS,
NMOS and TTL IC
