74V1G126

® 74V1G126 SINGLE BUS BUFFER (3-STATE) PRELIMINARY DATA s s s s s s s s HIGH SPEED: tPD = 3.8 ns (TYP.) at VCC = 5V LOW POWER DISSIPATION: ICC = 1 µA (MAX.) at TA = 25 oC HIGH NOISE IMMUNITY: VNIH = VNIL = 28% VCC (MIN.) POWER DOWN PROTECTION ON INPUTS SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 8 mA (MIN) BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 5.5V IMPROVED LATCH-UP IMMUNITY S (SOT23-5L) C (SC-70) ORDER CODE: 74V1G126S 74V1G126C 3-STATE control input G has to be set LOW to place the output into the high impedance state. Power down protection is provided on all inputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V. DESCRIPTION The 74V1G125 is an advanced high-speed CMOS SINGLE BUS BUFFER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.
