DESCRIPTION
SOP TSSOP Table 1: Order Codes PACKAGE SOP TSSOP T&R 74VHCT541AMTR 74VHCT541ATTR In order to enhance PC board layout, the 74VHCT541 offers a pinout having inputs and outputs on opposite sides of the package. 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. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
