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
