electronicsThe TM74HC138 is a 74 Series component manufactured by Titan Microelectronics. It is a high-performance, 3-3V ~ 5V SOP-16_150mil RoHS-compliant, three-state hex inverting buffer designed for both direction bus interfaces. This part has a propagation delay of 420 ns max and a power dissipation of 400 mW max. It has built-in 3-state output latched and low-input current Schmitt trigger input buffers, making it suitable for address decoding, driving multiple load capacitance and multiplexes. Its 3-state outputs are suitable for driving TTL, TTL open drain, DTL, MOS, and CMOS logic levels.
