Overview: ® 74VHCT240A OCTAL BUS BUFFER WITH 3 STATE OUTPUTS (INVERTED) s s s s s s s s s s HIGH SPEED: tPD = 5 ns (TYP.) at VCC = 5V LOW POWER DISSIPATION: ICC = 4 µA (MAX.) at TA = 25 oC PATIBLE WITH TTL OUTPUTS: VIH = 2V (MIN), VIL = 0.8V (MAX) POWER DOWN PROTECTION ON INPUTS & OUTPUTS SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 8 mA (MIN) BALANCED PROPAGATION DELAYS: tPLH ≅ tPHL OPERATING VOLTAGE RANGE: VCC (OPR) = 4.5V to 5.5V PIN AND FUNCTION PATIBLE WITH 74 SERIES 240 IMPROVED LATCH-UP IMMUNITY LOW NOISE: VOLP = 0.9V (Max.) M (Micro Package) T (TSSOP Package) ORDER CODES : 74VHCT240AM 74VHCT240AT G output enable governs four BUS BUFFERs. This device is designed to be used with 3 state memory address drivers, etc. Power down protection is provided on all inputs and outputs and 0 to 7V can be accepted on inputs with no regard to the supply voltage. This device can be used to interface 5V to 3V. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
