SOP TSSOP Table 1: Order Codes PACKAGE SOP TSSOP T&R 74VHCT541AMTR 74VHCT541ATTR DESCRIPTION The 74VHCT541A is an advanced high-speed CMOS OCTAL BUS BUFFER (3-STATE) fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. The 3 STATE control gate operates as two input AND such that if either G1 and G2 are high, all eight outputs are in the high impedance state. 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. This device can be used to interface 5V to 3V since all inputs are equipped with TTL threshold. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
