16-bit edge-triggered D-type flip-flop; 3-state
Rev. 04 — 4 July 2005
Product data sheet
1. General description
The 74ALVT16374 is a high performance BiCMOS product designed for VCC operation at 2.5 V or 3.3 V with I/O compatibility up to 5 V.
This device is a 16-bit edge-triggered D-type flip-flop featuring non-inverting 3-state outputs. The device can be used as two 8-bit flip-flops or one 16-bit flip-flop. On the positive transition of the clock (CP), the Q outputs of the flip-flop take on the logic levels set up at the D inputs.
2. Features
s 16-bit edge-triggered flip-flop s 5 V I/O compatible s 3-state buffers s Output capability: +64 mA and −32 mA s TTL input and output switching levels s Input and output interface capability to systems at 5 V supply s Bus-hold data inputs eliminate the need for external pull-up resistors to hold unused
inputs s Live insertion and extraction permitted s Power-up reset s Power-up 3-state s No bus current loading when output is tied to 5 V bus s Latch-up protection exceeds 500 mA per JESD78 s Electrostatic discharge protection:
x MIL STD 883 method 3015: exceeds 2000 V x Machine model: exceeds 200 V
