TC74VCX125FT

The TC74VCX125FT is a high performance CMOS QUAD BUS BUFFER which is designed for use in 1.8, 2.5 or 3.3 Volt systems, it achieves high speed operation while maintaining the CMOS low power dissipation. It is also designed with over voltage tolerant inputs and outputs up to 3.6V. All inputs are equipped with protection circuits against static discharge. This device requires 3-state control input OE to be set high to place the output into the high impedance state.

The features of TC74VCX125FT can be summarized as (1)low voltage operation: VCC = 1.8~3.6V; (2)high speed operation: tpd = TBD (max.) at VCC = 3.0~3.6V/tpd = TBD (max.) at VCC = 2.3~2.7V/tpd = TBD (max.) at VCC = 1.8V; (3)3.6 tolerant inputs and output; (4)output current: (IOH/IOL) = ±24 mA (min.) at VCC = 3.0V/(IOH/IOL) = ±18mA(min.) at VCC = 2.3V/(IOH/IOL) = ±6mA (min.) at VCC =1.8V; (5)latch-up performance: ±300mA; (6)ESD performance: human body model > ±2000V/machine model > ±200V; (7)package: TSSOP (Thin shrink small outline package); (8)power down protection is provided on all inputs and outputs. (9)support live insertion/withdrawal (To ensure the high-impedance state during power up or power own, OE shoud be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sourcing capability of the driver.).

The absolute maximum ratings of TC74VCX125FT are (1)VCC power supply voltage: -0.5~4.6V; (2)VIN DC input voltage: -0.5~4.6V; (3)VOUT DC output voltage(VCC = off-state/high or low state, IOUT absolute maximum rating must be observed): -0.5~4.6/-0.5~VCC + 0.5V; (4)IIK input diode current: -50mA; (5)IOK output diode current(VOUT < GND, VOUT > VCC): ±50mA; (6)IOUT DC output current: ±50mA; (7)PD power dissipation: 180mW; (8)ICC/IGND DC VCC/Ground Current: ±100mA; (9)Tstg storage temperature: -65~150°C.
