Products Detail

The CDx4HC(T)259 is an 8-bit addressable latch featuring buffered inputs and outputs, four operating modes, and typical propagation delay of 15ns at Vcc=5V, CL=15pF, TA=25°C. It offers fanout of 10 LSTTL loads for standard outputs and 15 LSTTL loads for bus driver outputs, wide operating temperature range (-55°C to 125°C), balanced propagation delay and transition times, and significant power reduction compared to LSTTL logic. HC types operate from 2V to 6V with high noise immunity (30% of Vcc), while HCT types operate from 4.5V to 5.5V with direct LSTTL input compatibility (VIL max=0.8V, VIH min=2V) and CMOS input compatibility (I ≤ 1µA).
