PI74LPT16373
Fast CMOS 3.3V 16-Bit
Transparent Latch
Features
Description
• Compatible with LCX™ and LVT™ families of products
Pericom Semiconductor’s PI74LPT16373 is a 16-bit transparent
latchdesignedwith3-stateoutputsandareintendedforbusoriented
applications. The Output Enable and Latch Enable controls are
organized to operate as two 8-bit latches or one 16-bit latch. When
Latch Enable (LE) is HIGH, the flip-flops appear transparent to
the data. The data that meets the set-up time when LE is LOW is
latched. WhenOEisHIGH, thebusoutputisinthehighimpedance
state.
• Supports 5V Tolerant Mixed Signal Mode Operation
– Input can be 3V or 5V
– Output can be 3V or connected to 5V bus
• Advanced Low Power CMOS Operation
• Excellent output drive capability:
Balanced drives (24 mA sink and source)
• Pin compatible with industry standard double-density pinouts
• Low ground bounce outputs
The PI74LPT16373 can be driven from either 3.3V or 5.0V
devices allowing this device to be used as a translator in a mixed
3.3/5.0V system.
• Hysteresis on all inputs
• Industrial operating temperature range: –40°C to +85°C
• Multiple center pins and distributed Vcc/GND pins minimize
switching noise
• Packaging (Pb-free & Green available):
– 48-pin 240-mil wide thin plastic TSSOP (A)
– 48-pin 300-mil wide plastic SSOP (V)
