1 / 8 page 74AC244 OCTAL BUS BUFFER WITH 3 STATE OUTPUTS (NON INVERTED) April 1997 s HIGH SPEED: tPD = 4 ns (TYP.) at VCC =5V s LOW POWER DISSIPATION: ICC =8 µA (MAX.) at TA =25 oC s HIGH NOISE IMMUNITY: VNIH =VNIL = 28% VCC (MIN.) s 50 Ω TRANSMISSION LINE DRIVING CAPABILITY s SYMMETRICAL OUTPUT IMPEDANCE: |IOH|= IOL =24 mA (MIN) s BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL s OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V s PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 244 s IMPROVED LATCH-UP IMMUNITY DESCRIPTION The AC244 is an advanced CMOS OCTAL BUS BUFFER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C 2MOS technology. It is ideal for low power applications mantaining high speed operation similar to equivalent Bipolar Schottky TTL. G control output governs four BUS BUFFERs. This device is desibned to be used with 3 state memory address drivers, etc. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
