Both achieve high speed operation, similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The designer has a choice of complementary output (HC352) and 3 state output (HC353). Each of these data (1C0-1C3, 2C0-2C3) is selected by the two address inputs A and B. Separate strobe inputs (1G, 2G) are provided for each of the two four line sections. Taking the strobe input (1G, 2G) high inhibits the outputs. The output of HC352 is fixed at logic low level and the output of HC353 has a high impedance, unconditionally. All inputs are equipped with protection circuits against static discharge and transient excess voltage. October 1993 ……
