Hitachi HD74ALVCH16374
The HD74ALVCH16374 has sixteen edge trigger D type flip flops with three state outputs in a 48 pin package. 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.| Part No. | HD74ALVCH16374 |

DESCRIPTION
Data at the D inputs meeting set up requirements, are transferred to the Q outputs on positive going transitions of the clock input. 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

● VCC = 2.3 V to 3.6 V Typical VOL ground bounce < 0.8 V (@VCC = 3.3 V, Ta = 25°C) Typical VOH undershoot > 2.0 V (@VCC = 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.
