termination resistors; 5 V input/output tolerant; 3-state
FEATURES
• ESD protection:
HBM EIA/JESD22-A114-A
exceeds 2000 V
MM EIA/JESD22-A115-A
exceeds 200 V
• 5 V tolerant input/output for
interfacing with 5 V logic
• Wide supply voltage range of
1.2 to 3.6 V
• Complies with JEDEC standard
no. 8-1A
• CMOS low power consumption
• MULTIBYTE flow-through
standard pin-out architecture
• Lowinductancemultiple powerand
ground pins forminimum noiseand
ground bounce
• Direct interface with TTL levels
• All data inputs have bus hold
(74LVCH162374A only)
• High impedance when VCC=0
• Power off disables outputs,
permitting live insertion.
DESCRIPTION
The 74LVC(H)162374A is a 16-bit edge triggered flip-flop featuring separate
D-typeinputs foreachflip-flop and3-stateoutputs forbusoriented applications.
The 74LVC162374A consists of 2 sections of eight edge-triggered flip-flops.
A clock (CP) input and an output enable (OE) are provided for each octal.
Inputs can be driven from either 3.3 or 5 V devices. In 3-state operation,
outputs can handle 5 V. These features allow the use of these devices in a
mixed 3.3 and 5 V environment.
The flip-flops will storethe stateof their individual D-inputs thatmeet theset-up
and hold time requirements on the LOW-to-HIGH CP transition.
When OE is LOW, the contents of the flip-flops are available at the outputs.
When OE is HIGH, the outputs go to the high-impedance OFF-state.
Operation of the OE input does not affect the state of the flip-flops.
The74LVCH162374A bushold datainputs eliminates theneed forexternal pull
up resistors to hold unused inputs.
The 74LVC(H)162374A is designed with 30 Ω series termination resistors in
both HIGH and LOW output stages to reduce line noise.
