MM74HC125M, Буферы и линейные аппаратные драйверы 3-STATE Quad Buffers [SO-14]
The MM74HC125M is a 3-state general purpose high speed Non-inverting Buffer utilizing advanced silicon-gate CMOS technology. The quad buffer has high drive current outputs which enable high speed operation even when driving large bus capacitance. This circuit possess the low power dissipation of CMOS circuitry, yet have speeds comparable to low power Schottky TTL circuits. Both circuits are capable of driving up to 15 low power Schottky inputs. The MM74HC125 require the 3-state control input C to be taken high to put the output into the high impedance condition, whereas the MM74HC126 require the control input to be low to put the output into high impedance. All inputs are protected from damage due to static discharge by diodes to VCC and ground.
