Part Description: Low-Voltage 3-to-8 Line Decoder with 5-V Tolerant Inputs and Outputs


Part Details:

TC74LCX138F/FN/FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX138F,TC74LCX138FN,TC74LCX138FT,TC74LCX138FK Low-Voltage 3-to-8 Line Decoder with 5-V Tolerant Inputs and Outputs Note: xxxFN (JEDEC SOP) is not available in Japan. The TC74LCX138F/FN/FT/FK is a high-performance CMOS 3-to-8 decoder. Designed for use in 3.3-V systems, it achieves TC74LCX138F high-speed operation while maintaining the CMOS low-power dissipation. The device is designed for low-voltage (3.3 V) 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 and C) determine which one of the outputs ( Y0 - 7 Y ) will go low. When enable input G1 is held low or either 2A G or 2B G is held high, decoding function is inhibited and all outputs go high. G1, 2A G , and 2B G inputs are provided to ease cascade connection and for use as an address decoder for memory systems. All inputs are equipped with protection circuits against static discharge. Features · Low-voltage operation: VCC = 2.0 to 3.6 V TC74LCX138FN · High-speed operation: tpd = 6.0 ns (max) (VCC = 3.0 to 3.6 V) · Ouput current: |IOH|/IOL = 24 mA (min) (VCC = 3.0 V) · Latch-up performance: ±500 mA · Available in JEDEC SOP, JEITA SOP and TSSOP · Power-down protection provided on all inputs and outputs · Pin and function compatible with the 74 series (74AC/VHC/HC/F/ALS/LS etc.) 138 type TC74LCX138FT TC74LCX138FK Weight SOP16-P-300-1.27A : 0.18 g (typ.) SOP16-P-300-1.27 : 0.18 g (typ.) SOL16-P-150-1.27 : 0.12 g (typ.) TSSOP16-P-0044-0.65A : 0.06 g (typ.)
