SYMMETRICAL OUTPUT IMPEDANCE: |IOH| = IOL = 6mA (MIN) BALANCED PROPAGATION DELAYS: tPLH tPHL WIDE OPERATING VOLTAGE RANGE: VCC (OPR) = 2V to 6V PIN AND FUNCTION COMPATIBLE WITH 74 SERIES 540 DIP SOP TSSOP ORDER CODES PACKAGE DIP SOP TSSOP TUBE M74HC540B1R M74HC540M1R T&R M74HC540RM13TR M74HC540TTR DESCRIPTION The 74HC540 is an advanced high-speed CMOS OCTAL BUS BUFFER (3-STATE) fabricated with silicon C2MOS technology. The M74HC541 is an inverting buffer. The 3-STATE control gate operates as a two input AND such that if either G1 and G2 are high, all eight output are in the high impedance state. In order to enhance PC board layout the M74HC540 offer a pinout having inputs and outputs on opposite sides of the package. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
