M74HCT125 QUAD BUS BUFFER (3-STATE) s HIGH SPEED: tPD = 13ns (TYP.) at VCC = 4.5V LOW POWER DISSIPATION: ICC = 4µA(MAX.) at TA=25°C COMPATIBLE WITH TTL OUTPUTS : VIH = 2V (MIN.) VIL = 0.8V (MAX) BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 6mA (MIN) PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 125 ORDER CODES PACKAGE DIP SOP TSSOP TUBE M74HCT125B1R M74HCT125M1R T&R M74HCT125RM13TR M74HCT125TTR DIP SOP TSSOP s s s s s DESCRIPTION The M74HCT125 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 in to the high impedance state. The M74HCT125 is designed to directly interface HSC2MOS systems with TTL and NMOS components. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
