TC74VX162244FT

The TC74VX162244FT is a high-performance CMOS 16-bit bus buffer which is designed for use in 1.8V, 2.5V or 3.3V systems, TC74VX162244FT achieves high-speed operation while maintaining the CMOS low power dissipation. All inputs are equipped with protection circuits against static discharge. This device is non-inverting 3-state buffer having four active-low output enables. TC74VX162244FT can be used as four 4-bit buffers two 8-bit buffers or one 16-bit buffer. When the OE input is high, the outputs are in a high-impedance state. This device is designed to be used with 3-state memory address drivers, etc. The 26- series resistor helps reducing output overshoot and undershoot without external resistor. It is also designed with over voltage to lerant inputs and outputs up to 3.6V.

The features of TC74VX162244FT can be summarized as (1)26- series resistors on outputs; (2)low voltage operation: VCC = 1.8 to 3.6V; (3)high-speed operation: tpd = 3.3 ns (max) at VCC = 3.0 to 3.6V/tpd = 3.8 ns (max) at VCC = 2.3 to 2.7V/tpd = 5.7 ns (max) at VCC = 1.8V; (4)3.6V tolerant inputs and outputs; (5)output current: (IOH/IOL) = ±12 mA (min) at VCC = 3.0V/(IOH/IOL) = ±8mA(min) at VCC = 2.3V/(IOH/IOL) = ±4mA (min) at VCC =1.8V; (6)latch-up performance: ±300 mA; (7)ESD performance: human body model > ±2000V/machine model > ±200V; (8)package: TSSOP (Thin shrink small outline package); (9)power down protection is provided on all inputs and outputs; (10)supports live insertion/withdrawal(To ensure the high-impedance state during power up or power down, OE should 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 TC74VX162244FT are (1)VCC power supply voltage: -0.5 to 4.6V; (2)VIN DC input voltage: -0.5 to 4.6V; (3)VOUT DC output voltage(VCC = off-state/high or low state, IOUT absolute maximum rating must be observed): -0.5 to 4.6/-0.5 to 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: 400mW; (8)ICC/IGND DC VCC/Ground Current per supply pin: ±100mA; (9)Tstg storage temperature: -65 to 150°C.
