HD151244 octal buffers/line drivers with 3 state outputs ade-205-596 (z) 1st. edition dec. 2000 description the HD151244 using cmos process, provides high speed and high drivability equivalent to hd74ls240 with super low power dissipation. the device has eight inverter drivers (three state outputs) in 20 pin package. each four drivers construct a group and the two groups are controlled separately by 1 g and 2 g which enable the output at low level. power up down protection function keeps the output in high impedance state at low v cc regardless of the state in enable inputs. features high speed tpd = 10 ns (typ) high output current i oh = ?5 ma i ol = 24 ma both input and output is ttl level wide operating temperature: ta = ?0 to +85? both input and output is high impedance state at supply off the function provides power up down protection
