The 74HCT244 is an advanced high-speed
CMOS OCTAL BUS BUFFER (3-STATE) fabricated with silicon gate C2MOS technology. G control input governs four BUS BUFFERs. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
High Speed: tPD = 15 ns (TYP.) at VCC = 4.5V
Low Power Dissipation:
ICC = 4mA(MAX.) at TA=25°C
Compatible With TTL Outputs: VIH = 2V (MIN.) VIL = 0.8V (MAX)
Balanced Propagation Delays: tPLH @ tPHL
Symmetrical Output Impedance: |IOH| = IOL = 6mA (MIN)
Pin and Function Compatible With
74 Series 244
20 pin DIP. Actual brand may vary from picture.
