DESCRIPTION
The 74VHC244 is an advanced high speed CMOS OCTAL BUS BUFFER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology.
G output enable governs four BUS BUFFERs. This device is designed to be used with 3 state memory address drivers,

■ HIGH SPEED: tPD = 3.9 ns (TYP.) at VCC = 5V
■ LOW POWER DISSIPATION: ICC =4 µA (MAX.) at TA = 25 oC
■ HIGH NOISE IMMUNITY: VNIH = VNIL = 28% VCC (MIN.)
■ POWERDOWN PROTECTIONON INPUTS
■ SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 8 mA (MIN)
■ BALANCEDPROPAGATIONDELAYS: tPLH ≅ tPHL
■ OPERATING VOLTAGERANGE: VCC (OPR)= 2V to 5.5V
■ PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 244
