Overview
INTEGRATED CIRCUITS 74ALVCH16952 16-bit registered transceiver (3-State) Preliminary specification Supersedes data of 1994 Jul IC24 Data Handbook 1998 Sep 01 Philips Semiconductors Philips Semiconductors Preliminary specification 16-bit registered transceiver (3-State) 74ALVCH16952 FEATURES • Complies with JEDEC standard no.
8-1A • CMOS low power consumption • MULTIBYTETM flow-through pin-out architecture • Low inductance, multiple center power and ground pins for minimum noise and ground bounce DESCRIPTION The 74ALVCH16952 consists of two sections, each containing a dual octal non-inverting registered transceiver.
Two 8-bit back to back registers store data flowing in both directions between two bi-directional busses.
Data applied to the inputs is entered and stored on the rising edge of the clock (CPXX, where X is AB or BA) provided that the clock enable (CEXX) is LOW.
The data is then present at the 3-State output buffers, but is only accessible when the output enable input (OEXX) is LOW.
Data flow from A inputs to B outputs is the same as for B inputs to A outputs.
• Direct interface with TTL levels • Output drive capability 50Ω transmission lines @ 85°C QUICK REFERENCE DATA GND = 0V; Tamb = 25°C; tr = tf = 2.

CPD is used to determine the dynamic power dissipation (PD in µW): PD = CPD × VCC2 × fi + S (CL × VCC2 × fo) where: fi = input frequency in MHz; CL = output load capacity in pF; fo = output frequency in MHz; VCC = supply voltage in V; S (CL × VCC2 × fo) = sum of outputs.
