Product Summary
The TC74AC244FS is an advanced high speed CMOS octal bus buffer fabricated with silicon gate and double-layer metal wiring C2MOS technology. The TC74AC244FS achieves the high speed operation similar to equivalent Bipolar Schottky TTL while maintaining the CMOS low power dissipation. The TC74AC244FS is non-inverting. Both devices have two active-low output enables.
