SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 6mA (MIN) BALANCED PROPAGATION DELAYS: tPLH tPHL WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 125 DIP SOP TSSOP ORDER CODES PACKAGE DIP SOP TSSOP TUBE M74HC125B1R M74HC125M1R T&R M74HC125RM13TR M74HC125TTR DESCRIPTION The M74HC125 is an high speed CMOS QUAD BUFFER (3-STATE) fabricated with silicon gate C2MOS technology. The device requires the 3-STATE control input G to be set high to place the output into the high impedance state. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
