DESCRIPTION
The 74HCT240 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 = 4µA(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 240
