Микросхема SN74HC253N, КП12

Характеристики

SN74HC253N, КП12The SN74HC253N is a 4-line to 1-line dual Data Selector/Multiplexer with 3-state outputs. It contains inverters and drivers to supply full binary decoding data selection to the AND-OR gates. Separate output-control inputs are provided for each of the two 4-line sections. The 3-state outputs can interface with and drive data lines of bus-organized systems. With all but one of the common outputs disabled (in the high-impedance state), the low impedance of the single enabled output drives the bus line to a high or low logic level. Each output has its own OE input. The outputs are disabled when their respective OE is high.

• High-current inverting outputs drive up To 15 LSTTL loads
• Typical tpd = 9ns
• Permit multiplexing from n lines to one line
• Perform parallel-to-serial conversion
• ±6mA Output drive at 5V
• 1µA Maximum low input current
• 80µA Maximum low power consumption
• 3-state Version of HC153
