00 Mar 30, 2006 Description When the latch enable input is high, the Q outputs of HD74HC373 will follow the D inputs and the Q outputs of HD74HC533 will follow the inversion of the D inputs.
When the latch enable goes low, data at the D inputs will be retained at the outputs until latch enable returns high again.
When a high logic level is applied to the output control input, all outputs go to a high impedance state, regardless of what signals are present at the other inputs and the state of the storage elements.
Features • High Speed Operation: tpd (D to Q) = 16 ns typ (CL = 50 pF) • High Output Current: Fanout of 15 LSTTL Loads • Wide Operating Voltage: VCC = 2 to 6 V • Low Input Current: 1 µA max • Low Quiescent Supply Current: ICC (static) = 4 µA max (Ta = 25°C) • Ordering Information Part Name Package Type Package Code (Previous Code) Package Abbreviation HD74HC373P HD74HC533P DILP-20 pin PRDP0020AC-B (DP-20NEV) P HD74HC373FPEL HD74HC533FPEL SOP-20 pin (JEITA) PRSP0020DD-B (FP-20DAV) FP HD74HC533RPEL SOP-20 pin (JEDEC) PRSP0020DC-A (FP-20DBV) RP HD74HC373TELL TSSOP-20 pin PTSP0020JB-A (TTP-20DAV) T Note: Please consult the sales office for the above package availability.
