PI74FCT573T

PI74FCT373T PI74FCT573T Octal Transparent Latches Features: PI74FCT373/573T are pin compatible with bipolar FAST™ Series at a higher speed and lower power consumption TTL input and output levels Low ground bounce outputs Extremely low static power Hysteresis on all inputs www.DataSheet4U.com Industrial operating temperature range: –40°C to +85°C Device models available upon request Packaging: PI74FCT373T (Pb-free & Green available) – 20-pin TSSOP (L) – 20-pin QSOP (Q) – 20-pin SOIC (S) PI74FCT573T (Pb-free & Green available) – 20-pin QSOP (Q) – 20-pin SOIC (S) Description: Pericom Semiconductor’s PI74FCT373T and PI74FCT 573T are 8-bit wide octal transparent latches designed with 3-state outputs and are intended for bus oriented applications. When Latch Enable (LE) is HIGH, the flip-flops appear transparent to the data. The data that meets the set-up time when LE is LOW is latched. When OE is HIGH, the bus output is in the high impedance state.
