MM74HCT245N – TBC

The MM74HCT245N is a high-speed silicon-gate CMOS octal transceiver fabricated in a 20-pin plastic dual in-line package (PDIP). Functioning as a bidirectional buffer, it facilitates asynchronous data transmission between two buses. The device features non-inverting outputs and is specified for operation with a supply voltage (VCC) ranging from 4.5V to 5.5V. Its CMOS architecture provides high noise immunity and low power consumption, with quiescent current typically in the microampere range. Direction control (DIR) and output enable (OE) inputs govern the data flow direction and output state, respectively. When OE is high, the outputs are placed in a high-impedance state. The MM74HCT245N is pin-compatible with standard TTL logic devices, allowing for easy integration into existing systems. Propagation delay times are dependent on VCC and load capacitance, but are typically in the nanosecond range.
