TC74LCX138F

The TC74LCX138F is a high performance CMOS 3 to 8 DECODER.Designed for use in 3.3 volt systems, it achieves high speed operation while maintaining the CMOS low power dissipation.It is designed for low voltage VCC applications, but it could be used to interface to 5 V supply environment for inputs.When the device is enabled, 3 binary select inputs(A,B,C)determine which one of the output will go low.

Features of the TC74LCX138F are:(1)low voltage operation; (2)high speed operaiton; (3)output current; (4)latch-up performance; (5)available in JEDEC SOP, EIAJ SOP and TSSOP; (6)power down protection is provided on all inputs and outputs; (7)pin and function compatible with the 74 series.

The absolute maximum ratings of the TC74LCX138F can be summarized as:(1): supply voltage range(Vcc) is -0.5 V to 7.0 V; (2): DC input voltage(Vin) is -0.5 V to 7.0 V ; (3): DC output voltage(Vout) is -0.5 V to 7.0 V or -0.5 V to VCC + 0.5 V; (4): input diode current(IIK) is -50 mA; (5): output diode current(IOK) is +/- 50 mA; (6): DC output current(Iout) is +/-50 mA; (7): power dissipation(PD) is 180 mW; (8): storage temperature(Tstg) is -65 to +150.
