PDESCRIPTION teThe 74VHC240 is an advanced high-speed leCMOS OCTAL BUS BUFFER (3-STATE) ofabricated with sub-micron silicon gate and sdouble-layer metal wiring C2MOS technology. bG output enable governs four BUS BUFFERs. OThis device is designed to be used with 3 state -memory address drivers, etc. Table 1: Order Codes PACKAGE SOP TSSOP T&R 74VHC240MTR 74VHC240TTR Power down protection is provided on all inputs 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.
