Description
The HD74ALVCH16374 has sixteen edge trigger D type flip flops with three state outputs in a 48 pin
package. Data at the D inputs meeting set up requirements, are transferred to the Q outputs on positive
going transitions of the clock input. 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. Low voltage and high speed operation is suitable at the battery drive
product (note type personal computer) and low power consumption extends the life of a battery for long
time operation.
Features
• V_CC = 2.3 V to 3.6 V
• Typical V_OL ground bounce < 0.8 V (@V_CC = 3.3 V, Ta = 25°C)
• Typical V_OH undershoot > 2.0 V (@V_CC = 3.3 V, Ta = 25°C)
• High output current ±24 mA (@V_CC = 3.0 V)
• Bus hold on data inputs eliminates the need for external pullup / pulldown resistors.
