Texas Instruments CD74HCT243 High Speed CMOS Logic Quad-Bus Transceiver with 3-State Outputs CD74HCT243EE4

The CD74HCT243 is a high-speed CMOS logic quad-bus transceiver featuring three-state outputs, designed for efficient data communication. It offers a typical propagation delay of 7 ns at a supply voltage of 5 V and a capacitive load of 15 pF. The device supports a wide operating temperature range from -55°C to 125°C, making it suitable for various applications. It is compatible with both LSTTL and CMOS logic levels, with input thresholds of V_IL = 0.8 V (max) and V_IH = 2 V (min). The transceiver can drive up to 10 LSTTL loads for standard outputs and 15 LSTTL loads for bus driver outputs, ensuring robust performance in bus systems. The CD74HCT243 is available in a 14-pin PDIP package, making it easy to integrate into existing designs.
