General Description

These TRI-STATE buffers are general purpose high speed

inverting and non-inverting buffers that utilize advanced sili-

con-gate CMOS technology They have high drive current

outputs which enable high speed operation even when driv-

ing large bus capacitances These circuits possess the low

power dissipation of CMOS circuitry yet have speeds com-

parable to low power Schottky TTL circuits All 4 circuits are

capable of driving up to 15 low power Schottky inputs

The MM5474HC366 and the MM5474HC368 are inverting

buffers where as the MM5474HC365 and the MM54

74HC367 are non-inverting buffers The MM5474HC365

and the MM5474HC366 have two TRI-STATE control in-

puts (G1 and G2) which are NORed together to control all

six gates The MM5474HC367 and the MM5474HC368

also have two output enables but one enable (G1) controls

4 gates and the other (G2) controls the remaining 2 gates

All inputs are protected from damage due to static dis-
