TC7WT241FUTE12LF

Overview

The TC7WT241FUTE12LF is a high-speed CMOS dual bus buffer featuring non-inverted, 3-state outputs. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range from -40°C to 85°C. The device achieves a typical propagation delay of 13ns at VCC = 5V with a load capacitance of 15pF. Quiescent supply current is limited to a maximum of 2μA at 25°C. Output drive capability supports 15 LSTTL loads, with symmetrical output impedance providing a minimum source/sink current of 6mA.
