Description
When the latch enable (LE) input is high, the Q outputs of HD74HCT563 will follow the inversion of the D inputs and
the Q outputs of HD74HCT573 will follow 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
• LSTTL Output Logic Level Compatibility as well as CMOS Output Compatibility
• High Speed Operation: t_pd (Data to Q, Q) = 13 ns typ (C_L = 50 pF)
• High Output Current: Fanout of 15 LSTTL Loads
• Wide Operating Voltage: V_CC = 4.5 to 5.5 V
• Low Input Current: 1 µA max
• Low Quiescent Supply Current: I_CC (static) = 4 µA max (Ta = 25°C)
• Ordering Information
