Part Description: Low Voltage Quad 2-Channel Multiplexer with 5 V Tolerant Inputs and Outputs

Part Details:

TC74LCX157F/FN/FT/FK TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74LCX157F,TC74LCX157FN,TC74LCX157FT,TC74LCX157FK Low Voltage Quad 2-Channel Multiplexer with 5 V Tolerant Inputs and Outputs Note: xxxFN (JEDEC SOP) is not available in Japan. The TC74LCX157F/FN/FT/FK is a high-performance CMOS multiplexer. Designed for use in 3.3-V systems, it achieves TC74LCX157F 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. It consists of four 2-input digital multiplexers with common SELECT and ST inputs. When the ST input is held "H" level, selection of data is inhibited and all the outputs become "L" level. The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs. All inputs are equipped with protection circuits against static discharge. Features · Low-voltage operation: VCC = 2.0 to 3.6 V · High-speed operation: tpd = 5.8 ns (max) (VCC = 3.0 to 3.6 V) TC74LCX157FN · 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.) 157 type TC74LCX157FT TC74LCX157FK Weight SOP16-P-300-1.27A : 0.18 g (typ.)
