TC74VCX157FT

The TC74VCX157FT is a high performance CMOS MULTIPLEXER which 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. The SELECT decoding determines whether the A or inputs get routed to their corresponding outputs. All inputs are equipped with protection circuits agains static discharge. It is also designed with over voltage tolerant inputs and outputs up to 3.6 V. It consists of four 2-input digital multiplexers with common select and strobe inputs. When the STROBE input is held level, selection of data is inhibited and all the outputs become level.

The features of TC74VCX157FT can be summarized as (1)low voltage operation: VCC = 1.8~3.6V; (2)high speed operation: tpd = 2.5ns(max.) at VCC = 3.0~3.6V/tpd = 3.0ns (max.) at VCC = 2.3~2.7V/tpd = 5.0ns (max.) at VCC = 1.8V; (3)3.6 tolerant inputs and output; (4)output current: (IOH/IOL) = ±24mA (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.

The absolute maximum ratings of TC74VCX157FT 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.
